  Cuprous (I) oxide (Cu_{2}O) based solar cells were fabricated with the use of
the electrodeposition technique at nanometre scale, and the structural,
morphological and electrical properties were investigated. The Cu_{2}O layers
were electrodeposited on crystalline and polycrystalline copper substrates. To
complete the Cu_{2}O/Cu(100) and Cu_{2}O/Cu interfaces as the solar cells the
top electrodes of silver paste were painted on the rear of Cu_{2}O. The
theoretical analysis of the current voltage curve was provided to determine the
values of electrical parameters of the most efficient solar cell of
Ag/Cu_{2}O/Cu(100) and clearly indicate presence of two Schottky barriers at
interfaces.
