Özet
All inorganic perovskite materials consisting of Cs and Rb cations offer an exciting opportunity to fabricate more tunable absorber layers for highly stable solar cell devices. Herein, a 1D solar cell capacitance simulator (SCAPS-1D) is utilized to comprehensively study the photovoltaic performance of all-inorganic CsxRb1−xPbI3-based perovskite solar cells as a function of Cs content (x). The input parameters of SCAPS 1D, such as electron and hole mobilities, are evaluated as a function of x for CsxRb1−xPbI3. Equations for x-dependent photovoltaic parameters are derived. Superstrate n–i–p solar cell processed with architecture of ITO/TiO2/CsxRb1−xPbI3/P3HT/Au achieves a promising power conversion efficiency of over 11%. Simulations are also carried out to determine device performance by varying interface defects, series, and shunt resistance as a function of x. The device that obtained x = 0.2 of Cs content withstands various rigorous effects of varying interface defects, series, and shunt resistance. The findings presented herein will promote the development of all-inorganic CsxRb1−xPbI3 perovskite-based solar cells.
