Perovskite/Silicon tandem solar cells have earned substantial attention in the field of photovoltaics (PVs) due to their potential high-efficiency energy conversion. The provided TCAD simulation in the current work aims at delivering a novel design for a 4-T Perovskite/PERL p-type Si tandem solar cell. The main structure consists of ITO/CuSCN/Perovskite/PC60PM/AZO/ AgNW as the top cell and a conventional PERL p-Si as the bottom cell. Simulation results showed that the proposed top cell structure achieves a significant performance after substituting Zn(O0.3,S0.7) for AZO and PC60PM electron transport layers (ETLs), while replacing CuSCN with CuI as a suitable alternative for the hole transport layer (HTL). These modifications achieved an efficiency of 19.81% for the top cell. The bottom cell also attained a noteworthy level of performance by using bifacial dual-side-textured construction with efficiencies reaching 29.11% and 14.08% for bare and filtered cells, respectively. With these combined modifications, the PCE (power conversion efficiency) reached 33.89%, showing significant improve- ment compared to the base structure. |
