TL;DR: A new oxidizing route to ensure efficient removal of ZnSe is presented based on treatment with a mixture of an oxidizing agent and a mineral acid followed by treatment in an aqueous Na2S solution, with a large improvement on the conversion efficiency of the devices and an improvement of all the optoelectronic parameters of the cells.

TL;DR: Pentenary Cu2ZnSn(S(y)Se(1-y))4 (kesterite) photovoltaic absorbers are synthesized by a one-step annealing process from copper-poor and zinc-rich precursor metallic stacks prepared by direct-current magnetron sputtering deposition.

TL;DR: In this paper, the authors demonstrate the potentiality to produce solar cells based in earth abundant materials deposited onto low weight and flexible stainless steel substrates, using thermal treatments optimized for glass substrates.

TL;DR: In this paper, thin films with different compositions were prepared and thermally annealed to investigate its compositional and physical properties and its performance as absorber layers in solar cells.

TL;DR: In this paper, the optical non-destructive assessment of the relative Ga content in Cu(In,Ga)Se2 absorbers synthesized from electrodeposited precursors using combined photoluminescence (PL) and Raman scattering was performed.
