Are tin-based perovskite solar cells defective?

Defect is unavoidable in solution-processed Tin-based perovskite compounds. Defect plays an important role in the photovoltaic parameters and stability of Tin-based perovskites and their devices. Tin-based perovskite solar cells have exhibited great potential for their small bandgap, high carrier mobility, and non-toxic property.

Why do tin based perovskite solar cells show low open circuit voltage?

Tin (Sn) -based perovskite solar cells (PSCs) normally show low open circuit voltage due to serious carrier recombination in the devices, which can be attributed to the oxidation and the resultant high p-type doping of the perovskite active layers.

How do doped semiconductors improve the performance of heterojunction solar cells?

The use of doped semiconductors in heterojunction solar cells has improved device performance significantly by shifting the energy levels of the electron and hole transport layers.

Are tin halide perovskite solar cells efficient?

Adv. Energy Mater. 8, 1702019 (2017). Wang, F. et al. 2D-quasi-2D-3D hierarchy structure for tin perovskite solar cells with enhanced efficiency and stability. Joule 2, 2732–2743 (2018). Li, M. et al. Tin halide perovskite films made of highly oriented 2D crystals enable more efficient and stable lead-free perovskite solar cells.

Does tin oxidation affect photovoltaic performance?

Consequently, tin oxidation and its corresponding defective behavior seriously affect the device photovoltaic performance including output photovoltage and power conversion efficiency. We summarize these methods to suppress tin oxidation, such as tin halide compensation, reducing agents, composition and morphology optimization, and encapsulation.

Does the doping density of the electron transport layer affect the performance?

It is found that the doping density of the electron transport layer (TiO 2) and absorber layer (CsSnI 3) has a significant effect on the band alignment and thus on the device performance; however, an increase in the acceptor doping density of the hole transport layer (CuSCN) does not make any significant changes in the device performance.
