Cadmium telluride solar cells for space applications, BIPV, unmanned aircraft
U.K. researchers have developed a flexible thin-film cadmium telluride (CdTe) solar cell for use in ultra-thin glass for space applications.
Perovskites stick together for better performance
Scientists in the U.S. demonstrated an additive that acts as a “molecular glue” within a perovskite solar cell. Treating the cells with this self-assembled monolayer material was shown to greatly improve their long-term performance, whilst also providing a boost to conversion efficiency. And the scientists further point out that the treatment relies on simple processing and readily available materials – good signs for its applicability in manufacturing.
Organic solar for optical wireless data receivers
Researchers in the United Kingdom have built a 14%-efficient organic PV device that can be used in high-speed optical wireless communication systems. The cell consists of a 4×2.5mm photoactive layer fabricated with a bulk heterojunction of a polymer donor and fullerene and non-fullerene acceptors.

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.
CNBM wants to set up GW-scale production of CdTe solar panels in China
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.
The best radiative cooling tech for PV arrays
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.
Industry reacts to India’s production-linked PV incentive scheme
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.
16.63%-efficient perovskite PV module via slot-die coating
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.
