Developed by an international team including Saudi Arabia’s KAUST and the Chinese Academy of Science, the solar cell is claimed to be one of the most efficient perovskite PV devices based on 3D/2D heterostructures built to date.

The researchers built the cell with a hole transport layer (HTL) based on PEDOT:PSS and were reportedly able to reduce the losses caused by this compound with the utilization of a thiocyanate additive. The champion lab-sized device achieved an open circuit voltage of 0.875 V, a short circuit current density of 31.84 mA cm−2, and a fill factor of 83.23%.

Mellow Energy claims its ML-Flex panel is currently the world’s largest flexible perovskite solar module. Available in five versions with power output ranging from 260 W to 300 W, the module measures 1,200 mm x 1,600 mm and weighs only 2.04 kg.

Researchers from Belgium and the University of Cyprus have completed outdoor stability tests of perovskite solar mini-modules providing two-years of data on stability performance. The tests showed that the modules’ performance loss rates during the burn-in period of perovskites ranged between 7% and 8% per month.

Central Japan Railway Co. and Sekisui Chemical have revealed plans to deploy flexible perovskite-based PV systems along the Tokaido Shinkansen train line in Japan. They are using thin, lightweight, flexible film-type perovskite solar cells.

Japanese plastics manufacturer Sekisui Chemical, which recently invested in a 100 MW perovskite solar production plant, announced its latest demonstration project at two sites owned by Japan’s MUFG Bank. The project aims to both raise awareness of practical applications of perovskite solar PV technology and to further verify durability, weather resistance, and performance.

Researchers in China claim to have built a perovskite solar cell that can effictively reduce ion migration and offer superior stability. The device utilizes an ultrathin membrane made of a polymeric material known as PDTBT2T-FTBDT (D18), which reportedly offers conformal coverage on the surface of perovskite film due to its high fluidity.

Japanese plastics manufacturer Sekisui Chemical is investing in a 100 MW production line to make lightweight perovskite solar panels for low load-bearing rooftops, with an operational start in 2027. It will also acquire a production facility from Japanese electronics manufacturer Sharp.

New research from India has shown that bifacial perovskite solar cells can achieve a 2% higher power conversion efficiency with a tilt angle of 20 degrees. The scientists also developed a bifacial perovskite solar cell for applications in both tandem or single-junction PV devices.

Waaree Energies says it has agreed to support IIT Bombay in creating an advanced fabrication and characterization setup to develop high-efficiency perovskite solar cells.
