Scaling perovskite tandems’ U.S. prospects Three US manufacturers actively working to commercialize their respective perovskite-silicon tandem technologies make the case for tandem modules. CubicPV, Caelux and Swift Solar argue a commercial future for perovskites is inevitable, and they tell pv magazine the current policy environment could work in the technology’s favor.

Researchers identify main source of wide-bandgap solar perovskite degradation Scientists in Belgium have investigated how perovskite absorbers used in solar cell degrade under three different stress test types and have found that the interface between the perovskite layer and the electron transport layer suffers from weak thermomechanical stability, which creates the conditions for performance losses.

Inside perovskite solar cell durability and performance testing Accurately measuring the performance of perovskite solar cells and modules requires significant modifications to long-established testing standards used in silicon PV. Researchers are settling on methods that rely on up to several minutes of constant light exposure and other time-consuming procedures. These may be fine for the laboratory setting, but those looking to produce this technology at scale need standardized methods that can characterize cells and modules at a much faster rate.
