Korean researchers achieve world record efficiency of 23.64% for flexible perovskite-CIGS tandem solar cell
Scientists at the Korea Institute of Energy Research claim to have achieved the highest efficiency ever reported for a perovskite-CIGS tandem solar cell with flexible, lightweight architecture. The device was also found to achieve “excellent” durability.
Trina debuts 5 MWh energy storage system
The Chinese manufacturer said its new utility-scale battery uses 314 Ah cells with a 15,000-cycle lifespan.
Scientists testing perovskite-silicon tandem solar cells with interdigitated back contacts
A research team in Iran has designed a four-terminal perovskite-silicon tandem solar cells with a 19.3%-efficient bottom heterojunction cell and a 12.7%-efficient perovskite top cell. Both subcells were conceived to have interdigitated back contacts, with the top cell reportedly helping to improve the tandem device’s light-trapping and efficiency.
