Additional file 1: of The Fabrication of Ordered Bulk Heterojunction Solar Cell by Nanoimprinting Lithography Method Using Patterned Silk Fibroin Mold at Room Temperature
The cross-section SEM images of layers within solar cell before (a) and after (b) the depositing of PCBM and LiF/Al layers on the top of P3HT nanograting film. The cross-section SEM images of layers within solar cell are shown to offer some relevant data about the thickness of each layer in the solar cell. (DOC 235 kb
