Tongwei has also secured another massive polysilicon order and Golden Glass has invested in more heterojunction solar cell capacity. Furthermore, China’s National Energy Administration (NEA) said 23.7 GW of new solar was deployed in China in the first five months of the year.

Researchers in China have developed a four-junction tandem perovskite/CIGS cell. They claim it is the most efficient device of its kind with an n-i-p structure thus far. They used a novel surface passivation strategy to improve the perovskite cell efficiency and fill factor.

Scientists in China have developed a new recycling process for PV modules that can recover intact silicon cells from end-of-life products, and process them back into wafers. As part of the recycling process, the wafers are purified and surface-treated, making them suitable for integration into new, high-efficiency cells and modules.

Jolywood has canceled a plan to invest in solar cell and panel production in Indonesia, while Hangzhou First Applied Material has said that it will invest $226 million in the expansion of its EVA film output capacity.

JinkoSolar has scored a 1 GW PV panel order in China and Risen suspended a $758 million private placement of shares.

Longi commissioned a 5 GW solar cell factory in Ningxia Province and Gokin Solar announced plans to build a 50 GW ingot factory in Sichuan Province. Furthermore, PV equipment manufacturer Jinchen supplied 2 GW of production lines to Adani Solar in India.

Toyota starts testing hydrogen cartridges for use in mobility, household applications in Shizuoka Prefecture. Meanwhile, China’s Shaanxi Normal University designed an aerogel method to substitute platinum with ruthenium in electrocatalytic water splitting, the US Department of Energy (DOE) is getting closer to fund the Bipartisan Infrastructure Law’s $8 billion program, and UAE-based companies are stepping up cooperation with Azerbaijan, Japan and South Korea.

Chinese panel maker DAH Solar has developed a rooftop PV module with a new design that is claimed to enable water to wash away dust without the need for manual cleaning operations. The panel is offered in five versions with power output ranging from 450 W to 470 W and efficiency spanning from 20.85% and 21.78%.

A Chinese metals industry group said the price of polysilicon is rising, just as Comtec Solar revealed that it is gearing up to sell off its shuttered wafer factories in Shanghai. Flat Glass, meanwhile, has announced plans to expand solar glass production capacity.

Chinese scientists have developed an ultralight solar cell with perovskite film based on a 3-µm-thick polymer. It purportedly has a power conversion efficiency in line with that of perovskite cells of conventional thickness.
