Cs ‐treatments in Kesterite Thin‐Film Solar Cells for Efficient Perovskite Tandems (Small 16/2024)

Thin-Film Solar CellsA facile CsF treatment enhances CZTSSe grain growth and phase homogeneity, resulting in effective charge transport and a favorable P-N junction. This leads to a significant performance enhancement in CZTSSe thin-film solar cells, increasing efficiency from 8.38% to 10.20%. The CsF-treated CZTSSe bottom cell is integrated into a mechanically-stacked perovskite/CZTSSe 4T tandem solar cell, achieving the highest reported tandem efficiency of 23.01%.
