    摘要: Fabricating a solar cell stack includes forming a nanopatterned polymeric layer on a first surface of a silicon wafer and etching the first surface of the silicon wafer to transfer a pattern of the nanopatterned polymeric layer to the first surface of the silicon wafer. A layer of reflective electrode material is formed on a second surface of the silicon wafer. The nanopatterned first surface of the silicon wafer undergoes a buffered oxide etching. After the buffered oxide etching, the nanopatterned first surface of the silicon wafer is treated to decrease a contact angle of water on the nanopatterned first surface. Electron donor material is deposited on the nanopatterned first surface of the silicon wafer to form an electron donor layer, and a transparent electrode material is deposited on the electron donor layer to form a transparent electrode layer on the electron donor layer.
