Copper (1) Oxide (Cu2O) is a non-stoichiometric semi-conductor. It is envisaged that this semiconductor could be used for the fabrication of low-cost solar cells. These solar cells have been fabricated by researchers using 100 micrometer thick copper sheets. For the purpose of this research, copper foil sample was oxidized in air between 2500C and 10500C. The oxide films grown were then investigated by means of SEM. This research produced Cu/Cu2O solar cells with copper sheet 100 micrometer thick using prolonged annealing times and different annealing temperatures to study the development that were achieved in solar cell performance. The investigation of morphology was taken by scanning electron microscopy and (I – V) curve have been carried out, a cell of 42mV open-circuit, voltage, Voc, 6.7 μ A. short circuit current, Isc and conversion efficiency of 1.42X10 -4℅ has been achieved .in this research also detected the effect of prolonged annealing time on the performance of Cu/Cu2O Schotkky barrier solar cell due to continuous reaction of cuprous oxide with oxygen.
