Hong Kong-based quality assurance provider Sinovoltaics reported Insolation Energy, Waaree Renewable Technologies, and Solex Energy maintained their top three spots in the ranking this quarter. The number of companies with healthier Altmann-Z scores stayed the same at nine.

The U.S.-based manufacturer of silicon solar PV technologies for space announced a project that requires it to manufacture, assemble and integrate 1 kW of solar cells and modules into a novel solar wing within a four-week time-period.

A U.S.-based collaboration between the National Renewable Energy Laboratory (NREL) and CubicPV has yielded a perovskite minimodule with certified efficiency of 24.0%. The two noted that it is the first time a U.S. effort has set a record in the perovskite mini module category.

Sofab Inks, a spinoff of University of Louisville, said its transport layer materials enable perovskite solar cells with greater stability, efficiency, and scalability compared to incumbent materials.

Researchers at University of Toledo produced antimony sulfide (Sb2S3) thin film solar cells with 7.69% power conversion efficiency after determining optimal hydrothermal deposition, post annealing, and light soaking conditions. Stability tests showed more than 95% of initial efficiency after ten months.

The Defense Advanced Research Projects Agency said a project team testing new optical wireless energy receiver technology was able to transfer 800 W of power to a receiver 8.6 km away in a 30 second transmission. It claims is a distance and power record amongst optical power beaming demonstration results.

An international team led by the U.S. National Renewable Energy Laboratory (NREL) has used ionic salt for the electron transport layer of a perovskite solar cell to improve device stability and performance. Test results showed a 26% power conversion efficiency with 2% degradation after 2,100 hours of 1-sun operation at 65 C.

Avery Dennison has introduced a line of UV-resistant, pressure-sensitive adhesive tapes for PV modules. The new products support applications such as frame mounting, cell fixation, busbar bonding, and junction box installation.

To make it easier to adopt building integrated PV (BIPV) as a glazing material, a group within the IEA Photovoltaic Power Systems Programme (IEA-PVPS) has tackled the solar heat gain coefficient (SHGC) calculation for BIPV. It is part of IEA PVPS Task 15 international standardization efforts.

After finding a way to make spiro-OMeTAD, a popular perovskite solar cell hole transport layer, less prone to heat-induced crystallization, researchers at Georgia Institute of Technology are now seeking partners to scale the technology for large-area PV cells.
