Are tin perovskite solar cells lead-free?

Continuous research efforts pushed the PCE of tin perovskite solar cells above 14%, making them one of the most promising “lead-free” materials. However, despite their increasing PCEs, tin-based devices are prone to degradation.

Is tin-based perovskite oxidation a problem for solar cells?

At present, the maximum power conversion efficiency of solar cells using inorganic tin-based perovskite layer as light absorber has exceeded 10%. We notice Sn 2+ oxidation is an unavoidable and critical issue for this type of device, representing unstable performing inferior to their lead-based counterparts.

How to improve tin perovskite solar cells efficiency?

To enhance solar cells efficiency, a deep knowledge of tin perovskite chemistry is needed. For example, solvent engineering has been shown to be a suitable method to enhance the efficiency of tin perovskite solar cells by improving crystallization and film quality.

Why are quasi-2D tin perovskite solar cells stable?

The achievement of such a remarkable stability in quasi-2D tin perovskite solar cells is attributed to the low-lying VBM and the bulky and hydrophobic organic spacer cations used, which form a protecting layer inhibiting the reaction between the tin perovskite layer and water and oxygen.

Why are Nip-type tin-based perovskite solar cells underperforming?

However, nip -type tin-based perovskite solar cells have underperformed largely due to the indiscriminate use of metal oxide electron transport layers originally designed for nip -type lead-based perovskite solar cells. Here, we reveal that this underperformance is caused by oxygen vacancies and deeper energy levels in metal oxide.

Does tin oxidation reduce defect density?

We began with the origins of the easier oxidation of Sn 2+ than Pb 2+, decomposition processes of inorganic tin perovskites, the effect of tin oxidation on the property of the material itself and the performance of their application in solar cells. Subsequently, the methods to reduce the oxidation of Sn 2+ and thus defect density are reviewed.
