Heterojunction organic solar cells made by sequential deposition of very thin films of cadmium sulfide (CdS) and magnesium phthalocyanine (MgPc) onto a conductive glass substrate have been studied. The short circuit photocurrent I/sub sc/ under AMO illumination approached 160 ..mu..A/cm/sup 2/ and an open circuit voltage of 0.69 V was obtained. The fill factor ff ranged from 20% to 40%. The action spectra and capacitance-voltage measurements indicated that the active region is located within the MgPc film at the CdS--MgPc interface. The optimum thickness of the CdS and MgPc layers have been found to be 100 and 60 nm, respectively. A band model of the heterojunction is proposed, which accounts for the observed results.
