Silicon solar cells step up

Silicon heterojunction solar cells represent a promising photovoltaic approach, yet low short-circuit currents limit their power conversion efficiency. New research shows an efficiency record of 26.81% driven by lower resistance loss and higher current by replacing the conventional front and rear amorphous doped-silicon layers with nanocrystalline layers.
