Scientists in Switzerland achieved 26.5% efficiency on a perovskite-silicon tandem cell measuring 4cm² and relying on industry-standard screen-printed metallization, further demonstrating the technology’s potential for large-scale production and low-cost electricity generation.

Few doubt that aluminum 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.

Scientists in Germany evaluated multiple silicon cell concepts based on both cost and efficiency in serving as the bottom layer in a perovskite-silicon tandem cell. The study, based on both simulation and experimental work, outlines advantages to various approaches with the silicon cell and concludes that in almost every case, perovskite-silicon tandem cells have the potential to bring solar costs down below what could be achieved with silicon alone.

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.

Deepak Thakur, CEO of the hybrid and energy storage business at Indian solar developer Sterling and Wilson, has spoken to pv magazine about the global market, and said: “Efficient and economically viable energy storage, and optimal hybridization, are crucial for ensuring the expansion of renewable power generation both at the grid and micro-grid scale.”

Guide to drawing up national green hydrogen strategies acknowledges the global hydrogen economy could fail to take shape if any of the world’s powers decide to stick with fossil fuels to gain a price advantage.

Scientists in Germany investigated printing processes for perovskite solar cells, making some important conclusions for the development of inks suitable for the deposition of perovskite cell materials onto a substrate.

The latest edition of the accountant’s renewables attractiveness index has placed the nation in top spot for photovoltaics, helping it to fourth spot for overall clean energy investment. Mexico has been hammered by the government’s attitude to clean power and France has also slipped, four places.

According to a new report by BloombergNEF, 58% of global passenger vehicle sales in 2040 will come from electric vehicles, yet they will make up less than 33% of all cars on the road.

It is now a well-established trend. After the switch to larger wafer sizes played out in 2019, this year has seen virtually all of the biggest PV manufacturers introduce new modules in dimensions above the 2-meter mark, and with power ratings in excess of 500 W – in some cases, as high as 800 W. As these modules begin to roll off production lines in larger quantities, it’s vital to take a look at the challenges and opportunities they bring to system design, installation, and long-term operation.
