to form a cdte layer then a carbon paste prepared by kneading carbon powder and a viscous agent made of a solution of a resin in an organic solvent was applied on the cdte layer to form an electricity collecting electrode 4 on the n cds p cdte heterojunction further the carbon electrode layer 4 and the cds layer 2 were provided with a positive terminal 5 and a negative terminal 6 of ag in by depositing ag in paste by screen printing and drying and baking the ag in paste being prepared by kneading of silver ag and indium in powders with a viscous agent made of a solution of a resin in an organic solvent on the positive and negative electrodes 6 and 5 of ag in copper paste was applied by screen printing and dried and baked further on the other parts of the cell a passivation layer was likewise applied by printing and dried and baked to complete the cell the sinterings or bakings in the above processes were made in a nitrogen atmosphere the following describes the effect of vibration given to the glass substrate when in the above described manufacturing process of a compound semiconductor solar cell the pastes made of the mixtures of the respective powdered n type and p type compound semiconductor materials flux agent and viscous agent were applied to form the n type and p type layers and electrode layers on the substrate a a sample cell fabricated with the semiconductor and electrode layers dried and fired after the application of the paste on the substrate without vibration i e according to the prior art b a sample cell fabricated with.
