Semitransparent Polymer Solar Cells Based on Liquid Crystal Reflectors

Semitransparent Polymer Solar Cells Based on Liquid Crystal Reflectors

The effects of liquid crystal (LC) reflectors on semitransparent polymer solar cells (PSCs) were investigated in this paper. By improving the cathode, we manufactured semitransparent PSCs based on the conventional PSCs. We then incorporated the LC reflector into the semitransparent PSCs, which incre...
