Controlling the Anionic Ratio and Gradient in Kesterite Technology [PDF]
ACS Applied Materials & Interfaces, 2022 Accurate anionic control during the formation of chalcogenide solid solutions is fundamental for tuning the physicochemical properties of this class of materials. Compositional grading is the key aspect of band gap engineering and is especially valuable at the device interfaces for an optimum band alignment, for controlling interface defects and ...

What is the bandgap of kesterite?
Solar Energy Materials and Solar Cells, 2016Abstract There are different ways to determine the bandgap of a semiconductor. In the case of strong tailing they lead to different results. Various versions of Tauc’s plot give the gap of extended states, whereas the photoluminescence and the quantum efficiency extend into the tail states.

Physica E: Low-dimensional Systems and Nanostructures, 2022
Abstract Here we present a monolithic kesterite-based tandem solar cell to harvest sunlight from a wide spectral range. The proposed tandem structure consists of a higher band gap Cu2ZnSnS4 (CZTS) top cell and an underlying lower band gap (AgxCu1-x)2ZnSnSe4 (ACZTSe) bottom cell connected in a series circuit through a tunneling junction.

On the origin of band-tails in kesterite
Solar Energy Materials and Solar Cells, 2018 Abstract Kesterite Cu2ZnSn( S x Se 1 − x )4 is an attractive earth-abundant material for low-cost thin film photovoltaics with the capability to achieve power production in the terawatt range and therefore to supply a significant part of the global electricity needs.

Countless rows of solar modules sit shimmering in the desert, a dark blue ocean stretching to the horizon. This is the Tengger Desert Solar Park in central China, by some estimates the world’s largest photovoltaic array, capable of generating up to 1.5 gigawatts of power. No wonder it’s been dubbed “the Great Wall of Solar Energy.” Arrays like this are

The Consequences of Kesterite Equilibria for Efficient Solar Cells
Journal of the American Chemical Society, 2011Copper-zinc-tin-chalcogenide kesterites, Cu(2)ZnSnS(4) and Cu(2)ZnSnSe(4) (CZTS(e)) are ideal candidates for the production of thin film solar cells on large scales due to the high natural abundance of all constituents, a tunable direct band gap ranging from 1.0 to 1.5 eV, a large absorption coefficient, and demonstrated power conversion efficiencies ...
