Basic schematic of a silicon solar cell. The top layer is referred to as the emitter and the bulk material is referred to as the base. Bulk crystalline silicon dominates the current photovoltaic market, in part due to the prominence of silicon in the integrated circuit market.
The typical lab efficiencies of monocrystalline cells are between 20% to 25%. In 2017, the Kaneka Corporation achieved the current highest efficiency record of 26.7%.
