Solution-based techniques are promising for fabrication of low-cost Cu2ZnSnS4 (CZTS) thin film solar cells (TFSCs). Annealing at high temperature with Se vapor has been widely applied to improve the performance of CZTS TFSCs. However, the mechanisms have been scarcely addressed in literatures. In this work, Se incorporation into sol-gel derived CZTS thin films was accomplished by introducing Se vapor...
In this paper, a novel type of nanostructured hybrid solar cell based on zinc oxide nanowires is proposed. The structure of the novel device is ITO/zinc oxide nanowire/poly(3-hexylthiophene-2,5-diyl) (P3HT): single walled carbon nanotube (SWCNT)/PEDOT:PSS/SWCNT. In order to clarify the charge transfer process in the proposed nanostructure, Kelvin Probe Force Microscopy (KPFM) is employed to study...
