Study on Dye-Sensitized Solar Cell by Screen Printing
ZHANG Ao, ZHANG Chun-mei, WU Wei-xia, WANG Duan-yang, YAO Song-ye, and MENG Tao
Presently, the study of dye-sensitized solar cells (DSSCs) has become one of the focus of solar cells research. Owing to low cost, easy fabrication process, and high power conversion efficiency (PCE), the DSSCs with the nano-crystalline porous TiO2 film as photo-anode by the preparation of screen printing are widely co
