Abstract
Emerging inorganic thin-film solar cells are attracting considerable attention for their huge potential of diverse applications scenarios in the modern and future society. While the power conversion efficiencies of these emerging thin-film solar cells are limited for some reasons, mostly associated with microscopic carrier loss mechanisms. In this seminar, I would like to talk about our recent work published on Nature Energy: How to identify the dominant microscopic carrier loss mechanisms in polycrystalline thin-film solar cells? Using Cu2ZnSnSe4 (CZTSe) as an example, we discuss how multiple micro- and macro-scale characterizations are applied to investigate the most important carrier transport and carrier recombination mechanisms, and how these characterizations are integrated with the 3D device simulations.
