Assessing the Impact of Alkali Post-Deposition Treatment on the Surface Properties of High-Efficiency Kesterite Absorbers.

The performance of kesterite solar cells has steadily improved over the past five years, driven by advances in molecular precursor composition and processing. Inspired by their success in high-efficiency chalcopyrite devices, alkali-salt post-deposition treatments (PDTs) have bee...
