RE+ was truly insane. The {Solar} Energy World editors are not any strangers to the tradeshow scene; we hit the bottom operating every present to seek out the most well liked merchandise and newest traits. However even we had been overwhelmed within the sea of 27,000 attendees — 27,000!! — and completed every day completely spent. My sneakers stuffed with blood! However I do it to remain on prime of all of the U.S. manufacturing rumors and see how batteries have gotten much more synonymous with the {solar} business.

SPW editors Kelsey and Kelly prepared for Day 1!

Now not the “Wild West,” I did hear many instances that the U.S. {solar} and storage (and even the EV) business is coming into a “gold rush” situation now with favorable laws and tax credit included within the Inflation Discount Act (IRA) — which is seemingly pronounced “Ira,” by the best way. However that rush to enter the market will demand extra standardization within the business’s merchandise. The U.S. renewable energy business has a desperate need for a trained workforce to fulfill these local weather objectives we’ve set. It’ll be much more tough to put in all these {solar} panels when contractors should be taught totally different strategies for various manufacturers of the identical product.

That’s my greatest takeaway from RE+: All the pieces is getting larger, whether or not it’s residential energy storage techniques or {solar} panels themselves — and there’s no consistency. Now not can we simply name {solar} panels 60-cell or 72-cell variations. Relying on wafer measurement and whether or not the cells are half-cut or use different expertise advances, {solar} panel sizes are in every single place. Seeing large-wafer {solar} panels in-person, and subsequent to earlier “historically sized” modules, it’s jarring. I do know I’m not the standard {solar} installer, however why can’t a 5-ft., 2-in. individual place panels on a sloped roof? It appears to be like completely not possible proper now with these massive modules.

Despite the fact that I can’t get my arms round them, that doesn’t make the developments in {solar} panel and battery designs any much less outstanding. Simply suppose how a lot has modified because the final {Solar} Energy Worldwide in 2019! I’m completely happy to current a few of my notable findings on the 2022 present right here. I hope you had been following along with me on Twitter all week.

Just a few footage of huge ole modules. The most important modules are for utility-scale installations, however even the shorter and wider modules for the DG market aren’t uniform in measurement throughout all manufacturers.

First {Solar} didn’t have a sales space, however its modules had been on show in its monitoring companions’. The brand new Sequence 7 module, which ought to begin popping out of its Ohio crops within the first half of 2023, makes use of twin metal again rails for simpler placement on trackers. Utilizing metal and no aluminum ought to assist with making the most of home metal manufacturing. The 540-W modules are 25% sooner to put in than its Sequence 6 design, in keeping with First {Solar} testing. All new First {Solar} factories being constructed (Ohio and a future one within the Southeast) can be solely devoted to this new module.

SunPower and First {Solar} announced earlier this year that they had been engaged on a tandem thin-film/crystalline-silicon {solar} module for the residential market. A CdTe thin-film layer will sit atop a layer of crystalline-silicon cells to seize extra of the solar’s energy. First {Solar} will make the module, and SunPower would be the unique supplier of the product to residential installers. SunPower mentioned that agreements have been signed between the 2 corporations, however now the expertise simply wants fine-tuning earlier than heading to market.

This was my most “wow” second on the present. Silfab is upending how we take into consideration {solar} panel manufacturing. The corporate has been working with a conductive backsheet from Endurans for a bit however is now taking it to the subsequent degree. The module cutaway on the proper of this image reveals the assorted layers. The backsheet can be set first, with back-contact {solar} cells over prime which have connecting factors particularly positioned for the conductive backsheet. There are not any busbars, which implies fewer probabilities for microcracking and busbar hotspots. The entrance of the Silfab module could be utterly black, with no interruptions, for unimaginable aesthetics for residential clients. These proprietary back-contact {solar} cells will must be manufactured near dwelling, so keep tuned for future U.S. manufacturing plans from the corporate.

Everybody has a battery now, and that’s not essentially a foul factor. Business improvement has allowed energy storage techniques to turn into bigger with larger capacities for “true” whole-home backup. The brand new EP Dice from Canadian {Solar} affords an excellent visible illustration of stackable batteries and higher-power inverters. The wires are condensed within the decrease sq. of this stack, battery cells are in between, after which the inverter is on prime. Primarily based on the capability wanted, battery modules might be added or eliminated within the stack.

There isn’t something particularly new in regards to the sonnenCore residential ESS, apart from its rising capability choices, however I share this picture to speak about sonnen’s new digital energy plant strategy in america. Together with installer Baker Residence Energy, sonnen has began a client battery program in California referred to as sonnenConnect/PowerOn! Sensible Battery Program. sonnen’s dwelling nation of Germany makes use of batteries virtually solely for grid interactions (backup energy shouldn’t be a priority there), so sonnen has tons of expertise on this space and is now managing a VPP in California with out particular utility-backing. sonnenConnect will function within the CAISO market, with sonnen managing buyer batteries, offering money rewards to clients (as an alternative of utility invoice credit) and contributing to the stabilization of California’s grid. We’ve already seen profitable VPPs with utility help within the Northeast and all through California, however this utility-independent mannequin may deliver extra worth to battery clients in Texas and different markets the place NEM is below menace.

Toshiba tests transparent solar cell layered on silicon cell for 9.5% efficiency



Toshiba tests transparent solar cell layered on silicon cell for 9.5% efficiency

Researchers at Toshiba in Japan have reported an development in output and reliability with its layered clear {solar} cell/silicon {solar} cell prototype.

Toshiba’s newly developed Cu2O {solar} cell delivers a excessive 9.5% effectivity.

The researchers have reported a clear cuprous oxide (Cu2O) {solar} cell with a conversion effectivity of 9.5%, the very best stage but achieved for a Cu2O cell. This was realized by enlarging its predecessor, announced in December 2021, and factors to the potential for mass manufacturing. The brand new cell is predicted to offer a lift for the event of EV that don’t require plug-in charging, and to advance different mobility functions, resembling high-altitude platform stations, telecom platforms within the stratosphere.

Tandem cells place a {solar} cell over a regular silicon cell. The cells generate energy at completely different wavelengths, elevating areal output, and have nice potential to spice up the effectivity of {solar} modules. Along with Toshiba’s clear Cu2O cell, work is being achieved on two different tandem cell applied sciences: fabrication with gallium arsenide (GaAs) or different III-V supplies; and perovskite crystal thin-films. Manufacturing prices for the previous vary from a number of hundred- to a number of thousand-times the price of a single silicon cell, severely limiting software. The latter can not but ship the required reliability and assured output for the 20-years-and-more lifetime of a silicon cell.

Toshiba’s R&D focuses on some great benefits of clear Cu2O cells: fabrication with naturally plentiful supplies cuts prices; a tough and powerful, and moisture resistant materials, all ensures of reliability; and lightweight transmittance qualities that open the way in which to excessive stage energy technology effectivity.

Schematic of Toshiba’s Cu2O-Si tandem {solar} cell.

Toshiba’s painstaking efforts at the moment are bearing fruit. In a analysis venture supported by Japan’s New Energy and Trade Expertise Growth Group (NEDO), researchers have pushed the conversion effectivity of the Cu2O cell to 9.5%, a full 1.1% over the 8.4% reported last year. It was achieved by enlarging the cell and suppressing service recombination within the fringe of Cu2O technology layer, which degrades technology effectivity.

“We discovered {that a} bigger cell dimension successfully suppresses photocarrier recombination,” explains Kazushige Yamamoto, a Fellow at Toshiba’s Company Analysis & Growth Middle, and chief of the analysis staff. “Growing the facility technology space from the earlier 3x3mm2 to 10x3mm2 produced a relative discount in recombination within the fringe of cell, and the ensuing improve in photocurrent pushed the effectivity to 9.5%.”

Prototype 40-mm2 clear Cu2O {solar} cell.

Toshiba has estimated that positioning the brand new Cu2O {solar} cell over a 25% environment friendly silicon cell realizes a Cu2O-Si tandem cell with a 28.5% effectivity — notably surpassing 26.7%, the very best reported effectivity for any customary silicon cell, and near 29.1%, the very best reported effectivity for any GaAs cell.

Underneath test criteria outlined by NEDO, Toshiba discovered {that a} one-time cost permits the present Cu2O-Si tandem cell to energy an electrical car for 37 km, and additional enhancements in {solar} cells towards the theoretical most effectivity of 42.3% are anticipated to increase the vary to a distance approaching 55 km. These are each acknowledged as sensible distances for brief journeys with out recharging, and would cut back charging frequency for longer journey.

Toshiba targets a sensible Cu2O-Si tandem cell with a ten% environment friendly Cu2O cell and an total effectivity of 30%, and the brand new cell data stable progress to that aim. Trying to mass manufacturing, the corporate is working to enlarge cell dimension, and has made a prototype with an influence technology space of 40mm2 and an effectivity round 8%. The effectivity falloff within the bigger cell is because of a much less uniform layer and Toshiba continues to refine skinny movie deposition know-how for uniform deposition over a bigger space.
