Özet

The effect of TiO2 thickness (60, 90, 120 nm) on performance of FTO/TiO2/P3HT:PCBM/Ag organic solar

cells (OSCs) was investigated. The cells were fabricated on both commercial fluorine-doped tin oxide (FTO)

and FTO coated on glass by ultrasonic spray pyrolysis (USP) method. While the efficiency of OSCs fabricated

on commercial FTO substrate was increased with increasing TiO2 thickness, there was no trend for the USP

deposited FTO substrates. The maximum efficiency of 0.51% was observed for the OSCs fabricated on

commercial FTO with the TiO2 thickness of 120 nm whereas the largest open circuit voltage was obtained for

USP deposited FTO with the TiO2 thickness of 90 nm.
