The absorber material CdSeTe/CdTe has a high absorption coefficient of 104cm1, allowing for extremely thin absorbers, with a graded bandgap from 1.40 to 1.50 eV, which is very close to the optimum for single junction solar cells. In this work, we have fabricated different absorber thicknesses ranging from 0.5 m to 0.8 m to study ultra-thin absorbers for CdSeTe/CdTe solar cells. Decreasing the absorber thickness, the costs and the environmental consumption are strongly reduced. In this paper, we analyze the impact of the thickness reduction on the electrical parameters of the devices containing Se. Currently, our best-performing ultra-thin CdSeTe/CdTe solar cell has an efficiency of 11 %

Abstract
The absorber material CdSeTe/CdTe has a high absorption coefficient of 104cm1, allowing for extremely thin absorbers, with a graded bandgap from 1.40 to 1.50 eV, which is very close to the optimum for single junction solar cells. In this work, we have fabricated different absorber thicknesses ranging from 0.5 m to 0.8 m to study ultra-thin absorbers for CdSeTe/CdTe solar cells. Decreasing the absorber thickness, the costs and the environmental consumption are strongly reduced. In this paper, we analyze the impact of the thickness reduction on the electrical parameters of the devices containing Se. Currently, our best-performing ultra-thin CdSeTe/CdTe solar cell has an efficiency of 11 %
