Abstract
Perovskite solar cells (PSCs) without a hole transport layer (HTL) are proposed in this 
study as a more cost-effective and efficient alternative to PSCs with an HTL. The active 
layer of these cells is CH3NH3SnI3
. To optimize the performance of the proposed PSC, 
different materials for Electron Transport Layers (ETLs) were simulated. Additionally, the 
impact of thickness, doping concentration, and doping concentration profile on device 
performance was investigated using a 1D-Solar Cell Capacitance Simulator. According to 
the simulation results, the optimal thicknesses of the ETL and the absorber were 30 nm and 
1000 nm respectively, resulting in a power conversion efficiency (PCE) of 31.08 %. The 
proposed HTL-free CH3NH3SnI3
.-based PSC attained an open circuit voltage of 1.1037 V, 
a short-circuit current density of 31.749 𝑚𝐴/𝑐𝑚2
, and a fill factor of 88.7 %. These results 
may help in the creation of highly effective and reasonably priced solar cells by providing 
insight into the design and optimization of HTL-free PSCs. Given that it provides a simple 
and inexpensive method of producing high-performance solar cells, the suggested PSC 
structure has the potential to be a viable replacement for traditional PSCs with HTL.
