Smart solar window based on thermochromic laminate
Dutch researchers have developed a solar window concept that blocks heat from the sun in warm weather and absorbs heat during colder periods.
Chinese PV Industry Brief: Trina starts building silicon-to-module factory, Jolywood opens TOPCon cell plant
Trina Solar has started building a silicon-to-module production base in Qinghai province, while Jolywood said it is now producing new TOPCon solar cells in Shanxi province. Tongwei, meanwhile, said it believes that its net profit soared in the first half.
All-perovskite tandem solar panel with 19.1% efficiency
German scientists have developed a two-terminal, all-perovskite solar panel with laser scribing and module interconnections. It has a fill factor of 75%.
Tesla’s solar trailer for range extension
Tesla has unveiled a fold-out solar trailer equipped with nine panels and a SpaceX Starlink satellite internet system.
More than 100,000 more Kenyan households could get solar after $8m investment
EU development body Edfi Electrifi and impact investor Oikocredit will each take a $4 million stake in Canadian off-grid home panel business Solar Panda.
One-third of global PV manufacturing capacity is at medium or high risk of bankruptcy, IEA says
A new report from the International Energy Agency stresses the importance of geographically diversifying the global PV supply chain. This would prevent supply chain vulnerability to bankruptcies and underinvestment.
No let-up in sight for polysilicon price hikes
A prominent analyst in China expects the price of the solar panel raw material to pass CNY 300 ($44.70) per kg soon and says the sky-high prices will continue at least through September.
CSEM, EPFL achieve 31.25% efficiency for tandem perovskite-silicon solar cell
The new world record was independently certified by the National Renewable Energy Laboratory (NREL) in the United States.
Thin film solar may have carbon intensity advantage over silicon
Thin-film cadmium telluride panels may have a $0.02 to $0.04 per watt carbon cost advantage over traditional polysilicon, said the National Renewable Energy Laboratory in an analysis of embodied carbon, embodied energy, and energy payback.
Near-invisible solar cell based on tungsten disulfide photoactive layer
Japanese scientists built a near-invisible solar cell based on indium tin oxide (ITO) and tungsten disulfide (WS2) as a transparent electrode and a photoactive layer, respectively. The cell has the potential to achieve a transparency of 79%.
