Abstract
Substitution of monocrystalline or polycrystalline silicon as active materials in
photovoltaics with highly efficient perovskite materials is quite
common. Although perovskite materials offer better flexibility, are
cost-effective, and have higher conversion efficiency, they still
require structural modifications for better performance. This study
quantitatively investigates how mesoporous top surfaces improve the
performance of methylammonium lead iodide (

) perovskite solar cells. In fact,
both the diameter and the depth of the pores have been tuned to
achieve better performance. The performance is further optimized by
replacing mesoporous active material with planar active material
coated with mesoporous indium tin oxide (ITO). We have demonstrated
that the proposed structure achieves the maximum conversion efficiency (

voltage (
