Abstract

Front electrodes of fluorine doped tin oxide (FTO) thin films and hole transporting layers of nickel oxide thin films have been combined to fabricate 1.063 cm2 inverted planar solar cells with cesium-containing triple cation perovskites as absorber layers. Using atmospheric pressure chemical vapor deposition FTO layers were obtained with low sheet resistance, decreased root mean squareroughness, increased transmission,and reduced optical haze values compared to a widely used commercial FTO substrate. Cell performance outperformed the equivalent cells fabricated using the commercial FTO. With full illumination under maximumpowerpoint tracking, a stabilized power conversion efficiency of 13.78 % was obtained for the champion device.
