Sažetak
Inorganic perovskite CaMnO3 was proposed as a substitution for the TiO2 anatase in electron transport layers of solar cells containing the hybrid perovskite CH3NH3PbI3 based on increased mobility of electrons and better optical matching. Due to suitable band gap concerning the absorption of sunlight, we investigate the potential of CaMnO3 and similar manganite perovskites, where Ca is replaced by either Sr, Ba or La, as an absorber layer in inorganic perovskite solar cells. In this study, we have used optical measurements on the synthesized AMnO3 (A = Ca, Sr, Ba, La) samples to aid density functional theory calculations (DFT) in order to accurately simulate the electronic and optical properties of AMnO3 compounds and gauge their potential for the role of absorber layer. Both experimental measurements and theoretical calculations show suitable band gap of 1.1-1.5 eV, depending on the compound, and absorption coefficients of the order of 10^5 cm^-1 in the visible part of the spectrum.
