Controlled synthesis of (hk1) preferentially oriented Sb2Se3 rod arrays by co-evaporation for photovoltaic applications

In this paper, we propose that the microstructural control of (hk1) preferentially oriented Sb2Se3 films from flat films to rod arrays can improve their photovoltaic efficiency by maximizing the carrier transport characteristics.

Flexible high-efficiency CZTSSe solar cells on stainless steel substrates

Stainless steel (SS) foil is made of abundant materials and is a durable and flexible substrate, but the efficiency of a solar cell on SS foil deteriorates via the diffusion of impurities from the SS substrate into a Cu2ZnSn(S,Se)4 (CZTSSe) absorber layer.

The effect of Ag alloying of Cu2(Zn,Cd)SnS4 on the monograin powder properties and solar cell performance

The reported results confirm that the positive effect of Ag in (Cu1−xAgx)1.85(Zn0.8Cd0.2)1.1SnS4 MGL solar cells appears only at very low Ag concentrations (x ≤ 1%).
