Korver Corp. was an American company with offices in California and China. Its mission was to develop high-efficiency perovskite/silicon tandem solar cells with sufficiently large area and long lifetime to be commercially manufactured.
These solar cells were planned to be significantly more efficient than typical silicon-based solar cells, with efficiency up to around 30-40% (compared to silicon-based which is 21-22%). Korver has reportedly modified the silicon material for its use as bottom solar cell, which optimized the design of the overall system, and the durability of the tandem cell. The perovskite and silicon are connected or “layered” using charge carrier transport layers.
