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.
Huasun achieves 34.02% efficiency for perovskite-heterojunction solar cell
The Chinese manufacturer said the result was achieved thanks to new perovskite crystallization additives and high-mobility carrier transport layer materials.
Renshine Solar hits 27.5% efficiency for flexible all-perovskite solar cell
Renshine Solar says it has achieved a record 27.5% efficiency for a flexible all-perovskite cell and 23.0% on a 20.26 cm² panel.
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.
Solaires Entreprises ships indoor perovskite PV modules to first customer
Solaires Enterprises, a Canadian perovskite startup, has begun supplying indoor PV modules for integration into sensor devices, marking its first commercial shipment.
