Abstract

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.
