Undoped and vanadium‐doped In 2 S 3 is used to fabricate pin ‐diodes. As p ‐type semiconductor two materials are compared: nano crystalline NiO and amorphous zinc‐cobalt‐oxid (ZCO). n ‐ZnO:Al (AZO) is used as electrode to In 2 S 3 . In 2 S 3 ‐films are grown by co‐evaporation, NiO‐ and ZCO‐films by pulsed laser deposition (PLD) and ZnO:Al‐films by RF sputtering. The diodes exhibit high current rectification of up to 3 and 6 orders of magnitude at ±2 V for diodes with p ‐NiO and p ‐ZCO, respectively. Diodes with p ‐type ZCO are used for solar cell analysis. Upon illumination both solar cell types with undoped and V‐doped In 2 S 3 as absorber material show photovoltaic activity. We find open‐circuit voltages of up to 300 mV and short‐circuit current densities of up to 0.29 mA cm −2 .
