This first comprehensive description of the most important material properties and device
aspects closes the gap between general books on solar cells and journal articles on …

Thin-film solar cells based on Cu2ZnSnS4 (CZTS) absorbers were fabricated successfully
by solid-state reaction in H2S atmosphere of electrodeposited Cu–Zn–Sn precursors. These …

The paper reviews the current status of the research on grain boundaries in polycrystalline
Cu (In, Ga)(S, Se) 2 alloys used as absorber materials for thin-film solar cells. We discuss …

Solar cells based on Cu (In, Ga) Se 2 absorbers are the most efficient ones among all thin
film photovoltaics. The current world record efficiency was attained by applying a rubidium …

We investigate the synthesis of kesterite Cu 2 ZnSnS 4 (CZTS) polycrystalline thin films
using cosputtering from binary sulfide targets followed by annealing in sulfur vapor at 500° C …

Abstract Recently, Ag incorporation into Cu (In, Ga) Se 2 structure was found to benefit the
solar cell performance. However,(Ag, Cu) 2 ZnSnS 4 used as the solar cell absorber is not …

The development of tandem photovoltaics and photoelectrochemical solar cells requires
new absorber materials with bandgaps in the range of≈ 1.5–2.3 eV, for use in the top cell …

The behavior of alkali atom point defects in polycrystalline CuInSe2 is studied. In this work,
three grain boundary models, one coherent twin boundary and two twin boundaries with …
