Abstract

We report a new semitransparent inverted polymer solar cell PSC with a structure of glass-FTO-nc-TiO2-P3HT:PCBM-MoO3-Ag-MoO3. Because high-temperature annealing which decreased the conductivity of indium tin oxide ITO must be handled in the process of preparation of nanocrystalline titanium oxide nc-TiO2, we replace glass-ITO with a glass-fluorine-doped tin oxide FTO substrate to improve the device performance. The experimental results show that the replacing FTO substrate enhances light transmittance between 400 and 600 nm and does not change sheet resistance after annealing treatment. The dependence of device performances on resistivity, light transmittance, and thickness of the MoO3-Ag-MoO3 film was investigated. High power conversion efficiency PCE was achieved for FTO substrate inverted PSCs, which showed about 75% increase compared to our previously reported ITO substrate device at different thicknesses of the MoO3-Ag-MoO3 transparent electrode films illuminated from the FTO side bottom side and about 150% increase illuminated from the MoO3-Ag-MoO3 side top side.
