Abstract:

A new highly structured In(OH)xSy/Pb(OH)xSy/PEDOT:PSS solar cell has been
developed based on the novel eta concept, and characterized by photovoltage spectroscopy, X-ray
photoelectron spectroscopy, scanning electron spectroscopy, photovoltaic response and quantum
efficiency spectroscopy. In this system, In(OH)xSy, PbS and PEDOT:PSS serve as electron conductor,
light photon absorber material and hole conductor respectively. The electron conductor and absorber
layer were prepared by chemical bath deposition, while the hole conductor was prepared by spin
coating technique. The band gap of as prepared In(OH)xSy has been found to vary with pH of the
solution; furthermore the bandgap of Pb(OH)xSy can be engineered to make it suitable as absorber
material.
