POLYMER SOLAR CELL USING A LOW-TEMPERATURE, SOLUTION-PROCESSED METAL-OXIDE THIN FILM AS A HOLE-EXTRACTION LAYER

摘要

A polymer solar cell includes a low temperature, solution-processed metal-oxide thin film, such as molybdenum-oxide (MoO_x), as a hole-extraction layer (HEW. The low temperature processing allows the metal-oxide thin film to achieve a smoother surface, which allows the thin film to have enhanced light transparency and increased electrical conductivity over that of conventional PEDOT:PSS thin films. As such, the polymer solar cell, which utilizes the metal-oxide thin film as a hole-extraction layer, is able to achieve enhanced power conversion efficiency over conventional polymer solar cells that use PEDOT:PSS as a hole-extraction layer.
