Fraunhofer ISE creates way to assess perovskite-silicon tandem PV modules
Fraunhofer ISE is leading a project that is developing methods to characterize perovskite-based tandem modules, in an effort to facilitate their industrial implementation. A specially built Wavelabs solar simulator is now being used at the institute’s CalLab PV Modules.
NASA makes unusual discovery while testing perovskite solar cells in space
NASA has discovered that perovskite solar cells tested in space exhibit less degradation than reference devices tested on Earth. The agency acknowledged that it is uncertain about the specific factors in the space environment that contributed to the superior performance of the perovskite absorber film.
Maxeon raises $199.4 million for IBC module manufacturing expansion
Maxeon Solar Technologies, the producer of the Maxeon and SunPower solar module brands, is raising capital from a $157.4 million underwriting of shares and a separate $42 million private placement with TCL Zhonghuan.
Indian researchers design lead-free perovskite PV cell with 31.57% efficiency
Researchers at India’s National Institute of Technology (NIT) Silchar, Assam, have designed a formamidinium tin iodide (FASnI3) active layer-based perovskite solar cell. It could potentially achieve a power conversion efficiency of 31.57%, while also scoring well on other performance parameters.
New design for 2T perovskite-silicon tandem solar cells with 24.6% efficiency
TU Delft scientists have built a tandem perovskite-silicon solar cell with a new approach to interface engineering. The device has an open-circuit voltage of 1.81 V, a short-circuit current of 18.1 mA/cm2, and a fill factor of 75.0%.
Canadian Solar ships 6.1 GW of modules in Q1
Canadian Solar shipped 6.1 GW of solar panels in the first three months of this year, up 68% from the first quarter of 2022.
Falling wafer prices continue to make headway for downstream prices
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
Inverted perovskite PV cell with silver thiocyanate HTL hits 16.66% efficiency
Egyptian researchers have developed a novel hole transport layer (HTL) for inverted perovskite solar cells using silver thiocyanate instead of the commonly used PEDOT:PSS and copper thiocyanate. The new HTL material demonstrated exceptional efficiency and stability in the constructed cell.
President Biden vetoes legislation to repeal moratorium on solar tariffs
Biden vetoed the repeal, saying it would undermine the efforts to ramp up domestic manufacturing to support a burgeoning solar industry and would create uncertainty for businesses and workers in the U.S. solar industry.
Tongwei led global polysilicon capacity in 2022, says Bernreuter Research
The world’s top four largest polysilicon producers in 2022 were Chinese companies, led by Tongwei with 345,000 metric tons (MT), followed by GCL Technology, Daqo, Xinte, and Wacker Chemie.
