Micro III-V solar cell with 33.8% efficiency

Developed by a French-Canadian research group, the triple-junction cell is based on indium gallium phosphide (InGaP), indium gallium arsenide (InGaAs) and germanium (Ge) and has an active area of only 0.089 mm2. It can be used for applications in micro-concentrator photovoltaics (CPV).

Indian incentives to support up to 13% of 240 GW of panel demand by fiscal 2030

India is targeting 280 GW of solar by 2030, of which 240 GW has yet to be built, but India Ratings says the country’s production-linked incentives will only cover up to 13% of future deployments.

Chinese PV Industry Brief: Zhonghuan raises wafer prices as president calls for faster action on emissions

Henan province immediately responded with a plan to deploy another 20 GW of solar and wind by 2025.

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.

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.

Semitransparent selenium solar cell for applications in tandem devices

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.
