The Chint Group has also said it was China’s largest PV plant owner at the end of 2020 with more than 5.7 GW in operation.
German PV production equipment provider Singulus will supply the vacuum coating systems for the new production. The Chinese conglomerate currently operates CIGS panel production facilities at four different locations in China.
Scientists in China have analyzed the radiative cooling techniques used in combination with solar energy systems such as PV arrays, solar thermal collectors, and concentrated PV installations. They identified five major system typologies based on functionality and working time.
The bifacial device showed a power conversion efficiency of 5.2% on the front side through an n-type contact and 2.7% on the rear side through a p-type contact.
Indian solar manufacturers have welcomed the bidding criteria for incentives to set up gigawatt-scale, high-efficiency PV production lines, but said that they would like a bigger budget to finance significant capacity build-out.
Scientists in China have developed a large-area perovskite solar panel by utilizing diphenyl sulfoxide (DPSO) as an electron acceptor. The device was fabricated via slot-die coating, and featured a parallel-interconnection architecture.
Furthermore, Luoyang Glass reported first-quarter net profits of RMB136 million (US$21 million) and TBEA Xinjiang New Energy announced the settlement of a dispute over a 99 MW wind farm.
Scientists in China took a closer look at the role of defects in limiting the performance of perovskite solar cells, demonstrating a screening effect that could be tuned to make material defects “invisible” to charge carriers, greatly improving cell performance. Using this approach they demonstrate a 22% efficient inverted perovskite solar cell, and theorize several new pathways to even higher performance.
Scientists in the United States discovered that hydrogen plays a leading role in the formation of defects in a perovskite film, which limit their performance as PV devices. The discovery, according to the researchers, offers further insight into observations already established by trial and error and could help to push the impressive efficiency achievements already made by perovskites even higher.
