Abstract

Thin TiO2 films are demonstrated to be an excellent electron-selective contact for crystalline silicon solar cells. An efficiency of 21.6% is achieved for crystalline silicon solar cells featuring a full-area TiO2 -based electron-selective contact.

Keywords: carrier-selective contacts; heterojunctions; solar cells; titanium dioxide.
