A collaboration between the U.S. National Renewable Energy Laboratory and the UNSW has yielded a new efficiency record of 32.9% for a tandem cell device utilizing III-V materials. Key to the achievement was a new technique enabling the researchers to take advantage of “quantum wells” in the material that serve to trap charges and enable tuning of the cell bandgap to absorb more of the light spectrum.

Perovskite developer Oxford PV has set a new world record for perovskite-silicon tandem cell efficiency at 29.52%, edging out the previous record set less than a year ago by Helmholtz Zentrum Berlin. The new record has been certified by the U.S. National Renewable Energy Laboratory.

The world is still combating Covid-19, with Europe now impacted by a second wave of the virus. While the market reported delays for a few projects, the impacts on the PV sector remain unclear. But if the world fails to curb the Covid-19’s spread, governments may be forced to reintroduce strict measures, thereby sapping PV demand. PV InfoLink’s Mars Chang expects module demand to hit 126 GW by the end of this year.

German standards body TÜV Rheinland is introducing a new testing and certification program for pv modules. The program incorporates component specific tests and ongoing, random testing of running production lines. Hanwha Q Cells assisted in the development of the program, and this week announced it is the first manufacturer to receive the new Quality Control PV Certification.

Use of the term “circular economy” is growing in virtually every industry worldwide – solar included. As noted throughout Q3, in the UP initiative’s focus on circular manufacturing, work is already underway to integrate circular principles into all areas of business, from internal operations and supply chain management to manufacturing and installations. In a recent analysis of PV recycling, BloombergNEF detailed six conclusions for the solar industry and those who are trying to make it more circular. Cecilia L’Ecluse, solar associate, and Julia Attwood, head of advanced materials at BloombergNEF share these conclusions as part of our quarterly theme on PV module recycling.

Scientists in the Netherlands are planning to build intelligent PV devices for energy and information applications. Their intention is to make this approach a new field of PV research, whose ultimate goal is enabling solar cells to communicate with each other and with other devices, ensuring that all the generated energy ends up exactly where it’s needed, especially in the urban environment.

The election of Joe Biden as U.S. president is set to heap further pressure on Australian Prime Minister Scott Morrison to lay out a clear and firm strategy charting the nation’s transition to a clean energy future.

A Dutch-Hungarian research team has measured, for 12 years, the degradation rates of PV modules installed in an off-grid system located in Ghana. It found that the panels had an average annual decline in power yield of 3.19%.

The solar manufacturer’s impressive third-quarter gross margin is set to fall back in the current three-month window because global shortages have seen some material costs double since the world came out of Covid-19 shock.

Few doubt that aluminium frames will be a part of the solar module for some time to come. And with PV manufacturing continuing to scale, the carbon footprint of this versatile metal may prove a sustainability challenge.
