Semitransparent organic solar cells

Abstract

The organic solar cell technology has attracted great interests due to its potential of low cost solution process capability. Bulk heterojunction organic solar cells offer a potentially much cheaper alternative way to harness solar energy, and can be made flexible and large area. They can also be made translucent and in different colors. As a result, the inexpensive fabrication process such as solution-process techniques, mechanical flexibility, light weight and visible-light transparency features make organic solar technology attractive for application in new markets, such as smart sensors, power generating window panes, building architecture, greenhouses and outdoor lifestyle, etc. After a brief overview of basics of organic photovoltaics, the enhancement of semitransparent organic solar cells over the two competing performance indices of power conversion efficiency and transmittance will be discussed.
