Article Synopsis
- Tin oxide (SnO) is widely used in perovskite solar cells but faces challenges due to defects that hinder charge transport.
- Doping SnO with ZnF effectively reduces these defects, improving electron transfer and decreasing energy loss from nonradiative recombination.
- The hybrid ETL enhances solar cell performance, achieving power conversion efficiencies of 21.31% and 24.91% for different perovskite types while maintaining about 90% efficiency after 600 hours of storage.
Tin dioxide (SnO), in perovskite solar cells (PSCs), stands out as the material most suited to the electron transport layer (ETL), yielding advantages with regard to ease of preparation, high mobility, and favorable energy level alignment. Nonetheless, there is a chance that energy losses from defects in the SnO and interface will result in a reduction in the . Consequently, optimizing the interfaces within solar cell devices is a key to augmenting both the efficiency and the stability of PSCs.

However, the high materials costs, complicated fabrication process, as well as poor long-term stability, are stumbling blocks for the commercialization of the PSCs in normal structures. The hole transport layer (HTL)-free carbon-based PSCs (C-PSCs) are expected to overcome these challenges.
