Paper Abstract

Hybrid solar cells based on a combination of conductive polymer poly (3,4-ethylenedioxyth1ophene) (PEDOT) doped with polystyrenesulfonate (PSS) and inorganic semiconductor CuIn(S,Se)2 (CISSe) were investigated. The CuInSe2 (CISe) absorber layers were electrodeposited on IT0 covered glasses from aqueous solutions with various ratios of elements. The ITO/In(O,S)/CISSe photovoltaic (PV) junctions were prepared by the sulfurization of ITO/CISe precursors at 450 °C in the H2S atmosphere. A PEDOT-PSS layer of p-type is considered as an alternative for the traditional window top layer on the CISSe absorber layer in the cell structure. The polymer deposition was performed using spin-casting technique. The PV properties of the prepared ITO/In(O,S)/CISSe and ITO/In(O,S)/CISSe/PEDOT- PSS structures were investigated, with special attention paid to the role of the conductive polymer layer in the cell structure.
