Abstract
Organic-inorganic heterojunction perovskite solar cells (PSCs) are of high interest due to their low manufacturing cost and higher power conversion efficiency (PCE). Hence, we study the opto-electro-thermal (OET) characteristics and investigate the optical and carrier transport and thermodynamic behaviors on the PSC. In this research, optical and electrical coupled behavior is investigated, and the results of this simulation are in the optimal state for nanoparticles (NPs) with a diameter of 50 nm: the short-circuit current (Jsc) of 18.05 mA/cm2, the open-circuit voltage (Voc) of 0.9406 V, and PCE of 14.15% were obtained. Then, by adding thermal behavior to optical and electrical physics, thermal effects and power losses in the solar cell were obtained. In this case, 221.5 W/m2 Joule heat, 154 W/m2 thermal heat, 123 W/m2 Peltier heat, and 92.3 W/m2 nonradiative heat waste power were achieved. Under these losses, the electrical parameters decrease. The parameters are Jsc=21.74 mA/cm2, Voc=0.94 V, and PCE=13.53%. The best case is obtained for the structure without NPs.
