Effect of annealing on conversion efficiency of nanostructured CdS/CuInSe2 heterojunction thin film solar cell prepared by chemical ion exchange route at room temperature

“…Among them, CdS/CuInSe 2 is considered as, promising nanomaterials for the development of solar cell owing to its tunable optoelectronic and physico-chemical properties, easy of synthesis, etc., these nanostructured heterojunction thin films can be grown by different routes such as physical and chemical, but achieving the desired stoichiometry, stability and the energy conversion efficiency are the topics of great concern, requiring extensive research. Nevertheless, the issues related to stoichiometry and stability can be resolved up to certain extent by preparing CdS/CuInSe 2 thin films using chemical ion exchange technique which has the merit that the film formed possesses homogenous interface between window (CdS) and absorber (CuInSe 2 ) layer [4,5], but improving the conversion efficiency in nanostructured CdS/CuInSe 2 thin films remains a challenge, extending the scope of the work [6,7]. As solar energy conversion is surface, interface and composition dependent phenomenon, the interface can be modified by ion exchange method, while surface and composition can be improved by providing post deposition treatments like annealing or swift heavy ion (SHI) irradiation [4,[8][9][10][11][12][13].…”

Growth and characterization of nanostructured CdS/Polyaniline/CuInSe2 thin films for solar cell applications

“…The solar energy conversion efficiency in such nanostructured CdS/CuInSe 2 thin films is defined by the observed open circuit voltage (Voc) and corresponding short circuit current (Isc) values of the thin films and these values basically depend on the interface formation, photo-generated charge transportation between window and absorber layer, density of charges etc. [5]. Therefore considering these aspects as major contender for solid state solar cell formation here in the present paper our ultimate aim is to prepare good interface thin films and try to reduce the mean free path required for photo-generated electron-hole transportation and separations.…”
