Band Gap Tuning of Cu2ZnGeSxSe4-x Absorbers for Thin-Film Solar Cells

Energies, 2017
In this work, kesterite-type Cu2ZnGeSxSe4-x absorbers were prepared by a two-step process for use in thin-film solar cells. Their high band gap makes them an interesting candidate as top cells in multijunction solar cells. However, an exact tuning of the

Advances in Se Wide‐Bandgap Photovoltaics and TexSe1‐x SWIR Photodiodes

Advanced Science, EarlyView.
In this review, fundamental properties and current challenges in Se photovoltaics (PVs) for tandem and indoor PVs and TexSe1‐x alloys for short wave infrared photodiodes are discussed. A case is made for the practicality of elemental chalcogenide optoelectronics, and a pathway toward resolving the key challenges in these respective technologies is ...

Multiple Synergistic Effects Enabling Efficient Kesterite Solar Cells via Introducing a Cu2O‐Bi2O3 Sacrificial Interlayer

Carbon Energy, EarlyView.
The Cu2O‐Bi2O3 thin film as a sacrificial interlayer at the back contact of kesterite solar cells achieves multiple synergistic optimizations in bulk defects, interface defects, back‐contact band offset, and MoSe2 properties. This enhances carrier separation, suppresses interface recombination, and enables DMSO‐processed kesterite devices to reach a ...

Kesterites and Chalcopyrites: A Comparison of Close Cousins [PDF]

MRS Proceedings, 2011
ABSTRACTChalcopyrite solar cells based on CuInSe2 and associated alloys have demonstrated high efficiencies, with current annual shipments in the hundreds of megawatts (MW) range and increasing. Largely due to concern over possible indium (In) scarcity, a related set of materials, the kesterites, which comprise Cu2ZnSnS4 and associated alloys, has ...
