This　article　demonstrates　a　facile　method　to　fabricate　a　solar　cell　based　on　p-Cu2O/n-ZnO　heterostructure,　which　was　constructed　through　n-ZnO　layer　deposition　by　radio　frequency　magnetron　sputtering　and　subsequent　p-Cu2O　film　cover　by　electrochemical　deposition　with　two　electrodes.　The　applied　potential　and　deposition　time　of　the　Cu2O　were　investigated　and　it　was　found　to　be　critical　to　the　morphologies,　microstructure,　and　optical　properties　of　the　heterojunction　solar　cells.　The　current　density-voltage　(J-V)　characteristics　of　p-Cu2O/n-ZnO　heterojunction　solar　cells　were　measured　and　show　well-defined　rectifying　behavior.　The　results　indicate　that　the　crystal　orientation　and　morphologies　of　the　Cu2O　play　key　roles　in　photovoltaic　conversion　efficiency　of　the　p-Cu2O/n-ZnO　heterojunction　solar　cell.　©　2015　Elsevier　B.V.　All　rights　reserved.
