Abstract:
Organic-inorganic halide perovskite solar cells (PSCs) have received significant research
attention due to their low processing cost and high performance. We have modeled perovskite
thin-film solar cell, p-i-n structure, with intrinsic layers of bulk methylammonium lead iodide
(CEkNEbPbb) and two-dimensional monolayer of CH3NH3PM3, which is mainly used to
enhance the stability of bulk CH3NH3Pbl3 layer. Poly (3,4-ethylenedioxythiophene)
polystyrene sulfonate (PEDOT: PSS), which is an organic hole transporting material (HTM),
has been used as a p-type layer. The material fullerene derivative (6,6)-phenyl-C61-butyric
acid methyl ester (PCBM), which is an organic electron transporting material (ETL), has been
used as an n-type layer. The performance of this perovskite solar cell model was simulated by
employing Solar Cell Capacitance Simulator (SCAPS-1D) under indoor low light conditions
and outdoor AM1.5G full Sun spectrum. The indoor light intensity produced by the artificial
light source is about 20 W/m2 as compared to the outdoor light intensity of 1000 W/m2. In this
work, Tungsten Halogen lamps were used as low light illumination sources to model the indoor
low light conditions. We have obtained the maximum power conversion efficiencies of the
baseline model of PSCs under spectrums of 10 W, 20 W, 50 W Tungsten Halogen Lamps, and
AM1.5G Sun as 11.47%, 12.04%, 12.16%, and 24.71% respectivelywith the open-circuit
voltages (Voc) of 1.07 V, 1.09 V, 1.12 V, and 1.26 V. According to these results, even for low
light conditions, we have obtained open-circuit voltages above 1.0 V and the device efficiencies
above 11% compared to outdoor light conditions.
