New Solar Panel Design Ups Efficiency 125 pct (New Prod & Tech)
University of York
Date: 2020-10-28
In the UK, a study led by researchers from the University of York in partnership with NOVA University of Lisbon reports designing solar panels in checkerboard lines improves diffraction to increase light absorption by 125 pct and lead to the production of thinner, lighter and more flexible solar panels.

Solar-grade silicon -- used to create solar cells -- is energy intensive to produce, so creating slimmer cells and changing the surface design would make them cheaper and more environmentally friendly, the study notes. The study suggests the design principle could impact not only the solar cell or LED sector but also applications such as acoustic noise shields, wind break panels, anti-skid surfaces, biosensing applications and atomic cooling.

LG Solar Launches High Efficiency Modules in US (Ind. Report)
LG Solar
Date: 2020-07-29
LG Business Solutions reports the U.S. launch of the latest "LG NeON® 2" 60-cell solar modules featuring higher efficiency and greater performance characteristics than current models.

The new modules feature a power class of up to 365 watts with a 21.1 pct module efficiency. With a better temperature coefficient, they also deliver a higher energy yield optimized for improved year-round performance. LG achieved the efficiency improvement by using larger wafers which reduce the white space between cells while keeping the traditional industry format of 60 cells for residential applications, according to the release.

JinkoSolar Claims Monocrystalline Silicon Cell Efficiency Record (Int'l)
JinkoSolar
Date: 2020-07-27
Shangrao, China-based solar module manufacturer JinkoSolar Holding Co., Ltd. is reporting the maximum solar conversion efficiency of its large-area N-type monocrystalline silicon solar cells reached 24.79 pct -- a world record for large-size contact-passivated solar cells. This result was independently confirmed by the Institute for Solar Energy Research in Hamelin (ISFH), Germany.

The record-breaking mono-crystalline silicon solar cell was fabricated on a CZ mono-Si substrate with a practical size of 267.72cm2. Several advanced technologies have been implemented to achieve this new record of 24.79 pct, including passivating contact technologies, advanced diffusion system, surface passivation and advanced anti-reflection technologies, as well as material upgrades integrated into the cell process. The record-breaking mono-crystalline silicon solar cell will be gradually applied to product production, according to the release.

NREL Claims 47.1 pct Solar Cell Efficiency Record (Ind. Report)
National Renewable Energy Laboratory
Date: 2020-04-20
Scientists at the National Renewable Energy Laboratory (NREL) are touting an innovative "six-junction" solar cell using 140 layers of semiconductor materials to achieve a conversion rate of 47.1 pct -- breaking the previous record set by the Fraunhofer Institute for Solar Energy Systems ISE and Soitec of 46 pct set back in 2014.

The NREL scientists produced a six-junction solar cell, combining sandwiching multiple layers of materials that were fine-tuned to convert different portions of the light spectrum into electricity. While the layered solar cell design will almost certainly be cost prohibitive to produce at commercial scale compared to conventional silicon cells, it may find use in more niche applications, the NREL team said. Generally, the super high-efficiency solar cells are limited for use in spacecraft and satellites, where performance, space and weight are a premium. However, the researchers highlight that cells with such high conversion efficiencies would be ideally used in concentrated solar plants.

The researchers trialled their nearly 50 pct efficient solar cells with concentrated sunlight, producing the equivalent of 143 suns of solar intensity. Using unconcentrated light, the six-junction solar cells were able to achieve a conversion efficiency of 39.2 pct, which was also a new world record.

Jinko Bifacial Modules Break Efficiency Record (New Prod & Tech)
JinkoSolar
Date: 2020-01-22
Shanghai-headquartered solar module manufacturer JinkoSolar Holding Co., Ltd. reports it has broken the world record for maximum conversion efficiency for its bifacial solar modules, hitting 22.49pct, as verified by TÜV Rheinland, an independent provider of technical services for testing, inspection, certification, consultation, and training.

To improve the efficiency of its mass-produced modules the company applied a newly developed anti-reflection coating (ARC) and advanced metallization technology alongside other proprietary technology and incorporated into the cell design, eliminating the inter-cell gapto ensure higher efficiency and reliability, according to a release.

According to its statement, JinkoSolar has an integrated annual capacity of 14.5 GW for silicon wafers, 9.2 GW for solar cells, and 15 GW for solar modules, as of September 30, 2019, according to the company.

EMPA Sets Flexible CIGS Solar Cell Efficiency Record (Int'l)
Empa Laboratory
Date: 2019-07-10
Swiss Federal Laboratories for Materials Science and Technology (EMPA) researchers report they have broken their own record and achieved a flexible CIGS solar cell efficiency of 20.8 pct -- 0.4 pct higher than the previous mark. The technology of choice is copper indium gallium diselenide (Cu(In,Ga)Se2) or CIGS, which enables the manufacture of flexible, lightweight solar cells on polymer films.

Flexible CIGS solar modules are already commercially available, in particular from the EMPA spin-off Flisom AG in Niederhasli, Switzerland, which was co-founded by Dr. Ayodhya Tiwari.

Risen Claims Multi-busbar Solar Cell Efficiency Record (Ind Report)
Risen Energy
Date: 2019-05-31
Chinese solar technology specialist Risen Energy Co. Ltd. is reporting its proprietary cast-mono five-busbar cell has achieved an efficiency of 22.05 pct while its multi-busbar monocrystalline cell has realized a maximum conversion efficiency of 23.08 pct and an average efficiency of 22.73 pct.

Risen's five-busbar cell includes double-sided passivation, antireflective films, electro-injection passivation and slurry improvement. This is the first time that a cast-mono five-busbar cell has successfully exceeded 22 pct in efficiency.

Compared with the five-busbar cell, the multi-busbar monocrystalline cell features a more optimized metallized contact technology, which effectively reduces the shading area, enhances the ability to collect carriers while reducing the incidence of cracks, contributing to a significantly higher conversion efficiency. A further cost reduction is realized with decreased use of silver slurry. (Source: Risen Energy, May, 2019) Contact: Risen Energy, Tel:0086-574-59953588, www.risenenergy.com

Imec, Jolywood Boast Record Solar Cell Efficiency (Ind. Report)
Imec, Jolywood
Date: 2019-04-10
Leuvin, Belgium-headquartered Imec reports its n-PERT (Passivated Emitter and Rear Totally diffused) solar cells developed with Jolywood, a Chinese manufacturer of n-type bifacial solar cells and modules, reached a certified front-side conversion efficiency of 23.2 pct, as certified by ISFH CalTec.

The developed n-PERT technology has a number of inherent advantages over p-type PERC cell technology, which is demonstrated in these newest cells: the potential for higher efficiencies because of lower sensitivity to metal impurities, and the absence of light-induced degradation (LID). Therefore, n-type PERT technology could become a cost-effective contender for -type PERC cells. To enable this, the current cells have a screen printed front grid and rear soldering pads which together amounts to less than 80mg of silver used per cell.

The bifacial n-PERT cells are expected to reach efficiencies above 23.5 pct, coupled to a bifaciality above 90 pct.
