Compared to current silicon-based solar cells that are rigid, organic-based solar cells that use solution-based processing or low-cost non-vacuum deposition techniques are simpler and less expensive to manufacture.
Organic solar cell can be made flexible, semitransparent and are light weight, offer more opportunities for application in new markets. Its unique flexibility and semi-transparency feature also adds a decorative and aesthetic dimension to the solar cells so that it can be used on curved and irregular surfaces – something that cannot be done using rigid silicon solar cells. After a brief overview of ITO-based transparent cathode fabrication, the enhancement of semitransparent organic solar cells over the two competing performance indices of power conversion efficiency and transmittance will be discussed. An optical admittance analysis is used to study the optical enhancement in poly(3-hexylthiophene) (P3HT): 1-(3-methoxycarbonyl)-propyl-1-phenyl-(6,6)C61 (PCBM)-based organic solar cells. The results of this work have yielded a promising mean external quantum efficiency of ~ 45% and a power conversion efficiency of 1.8% for a semitransparent organic solar cell having a 75 nm thick polymer blend of P3HT:PCBM. Our recent research progress in developing semitransparent organic solar cells will be presented.
