In hybrid solar cell, the SEM images showed the homogenously
distributed morphology of PEDOT, P3HT:PCBM, TiO2 layers. In IV
curve, all the films showed the Isc on Voc in dark and light. The film
having band gap 2.71 eV showed the highest Isc value in lowest Voc.
It means it has better photon response in visible spectrum and best
electron transportation in the device. The values of Isc and Voc are
very low because the device fabricated in ambient environment
had impurities, humidity, and oxygen which affected the device
