As the latest generation of photovoltaic technology, perovskite solar cells (PSCs) are explosively attracting attention from academia and industry (1–5).Although solar cell device is a complex system composed of multiple functional layers (), optimizing the perovskite film could generally contribute to the enhancement of final performance of PSCs (7–10).
In order to increase the PCE of organic solar cells and reduce energy losses , the construction of tandem organic solar cells is an effective strategy . In the tandem structure, there are two choices of active layer materials for the sub-cells.
Although solar cell device is a complex system composed of multiple functional layers (6), optimizing the perovskite film could generally contribute to the enhancement of final performance of PSCs (7 – 10). Previously, the preprepared or optimized perovskite films were assumed to be the same as the films actually working in the device (11 – 13).
Simulation results include the performance parameters of a solar cell (single-junction or tandem), i.e., open-circuit voltage (V OC), short circuit current density (J SC), fill factor (FF), and power conversion efficiency (PCE). The materials tested for ETL are TiO 2, PCBM, SnO 2 /PCBM compact ETL, and C 60.
In the field of organic photovoltaics, the power conversion efficiency of single junction solar cells continues to improve. However, tandem organic solar cells are poised to push the efficiency limits even further and offer a promising avenue for improving the performance of organic photovoltaic devices.
The results indicate that an increase in doping concentration of the absorber increased the Voc, FF and PCE but decreased the J SC of the solar cell. The interface between the ETM/back-electrode requires a cheap and low work function metal for enhanced performance.
The efficiency of the solar cells is directly related to the FF, as the FF increase, the efficiency of the device increases and hence the cell achieved 16.26% efficiency at 10 19 cm −3 doping density as shown in Fig. 3 d.
