Polycrystalline n ‐CdS/ p ‐CdTe solar cells with a commerical carbon paint on the p ‐CdTe layer and an In‐Ag paint on the n ‐CdS layer were fabricated by a coating and sintering method. Electrical properties of the conducting paints and solar cell parameters of the heterojunction solar cells were investigated as a function of electrode annealing conditions. The sintered CdS/CdTe solar cells whose electrode contacts were annealed at 350°C for 10 min in nitrogen showed maximum values of short‐circuit current density, fill factor, and solar efficiency. Commercial carbon and silver paints can be used as electrodes to fabricate sintered CdS/CdTe solar cells with efficiency over 10%.
