Glass/ITO/In(O,S)/CuIn(S,Se)2 solar cell with conductive polymer window layer

The PEDOT-PSS layer of p-type is considered an alternative to the traditional window top layer on the CISSe absorber layer in the cell structure. The polymer deposition was performed by help of the spin-casting technique. PV properties of the prepared ITO/In(O,S)/CISSe and ITO/In(O,S)/CISSe/PEDOT-PSS structures were studied, with emphasis on the role of conductive polymer layer in the cell structure.
