Abstract
A novel hybrid solar cell fabricated from TiO2 and in situ polymerized poly (thienylene methane) (PTBBQ) onto the surface of TiO2 was described. 1HNMR, FTIR, UV-Vis absorption, thermal and electrochemical properties of PTBBQ were investigated, and the surface morphology of TiO2/in situ polymerized PTBBQ film was studied via AFM contact mode. Device I/V characterizations with and without in situ polymerized PTBBQ were measured. Efficiency improvements were observed in the in situ polymerized PTBBQ/TiO2 system, and such device showed a short-circuit current density of 1.15 mA/cm2, an open-circuit voltage of 0.50 V, a fill factor of 0.50, and a energy conversion efficiency of 0.29% at A.M. 1.5 solar illumination (100 mW/cm2).
