We introduce two different methods for fabrication of polymer solar cells using printings and nano-templates. First, polymer solar cell devices was prepared by inkjet printing with modified PEDOT:PSS and P3HT:PCBM for hole transporting and photo active layer. The controlled printing parameters, such as drop formation behaviors, solvent mixtures and substrate temperatures, leaded to obtain pin-hole free surface films achieving power conversion efficiency of 3.5%. Second, conjugated polymer/methanofullerene nano-wire arrays were prepared by filling of P3HT:PCBM into the pores of anodic aluminum oxide (AAO) templates by simple coating methods. Well-aligned nano-wire arrays which have different diameters and lengths were obtained by changing the aspect ratios of the AAO templates. These structures were further used for fabrication of bulk heterojunction polymer solar cells. The device fabrications and photovoltaic characteristics of solar cell will be presented in details. |
