Abstract

The simulation of short-circuit current, open-circuit voltage, absorption coefficient, fill factor and efficiency of solar cell with p-i-n structure based on organo-trihalide perovskite semiconductors CH3NH3PbI3 was carried out. Simulated data obtained for the short-circuit current density ~15 31 A/cm2, the open-circuit voltage ~0.99 1.03 V, the absorption coefficient ~ , the fill factor ~82.1% 84.8%, and the efficiency ~14.85 % are in good agreement with the results of previous numerical and experimental data for perovskites solar cells
with similar composition and size. Closer to the edge of intrinsic absorption, both the short-circuit current and open-circuit voltage depend linearly on the wavelength of the incident irradiation. The calculations show the potential possibility of using perovskites in the design of tandem solar cells. The novelty of this work is the demonstration of the possibility of using thin layers of perovskite to convers solar energy. This material with direct bandgap energy provides good absorption of photons with energy>1.56 eV. In combination with the crystalline silicon, perovskite can broaden the absorption spectrum of irradiation, thereby increasing the power conversion efficiency of the tandem
solar cells.
