Abstract：

We　investigated　the　performance　of　the　inverted　polymer　solar　cells　with　an　electron　transport　layer　of　the　La-doped　TiO2　film.　The　different　La-doped　ratios　of　TiO2　films　were　prepared　by　a　simple　sol–gel　method.　The　device　with　0.5 mol%　La-doped　TiO2　film　shows　an　enhancement　of　the　power　conversion　efficiency　comparing　with　that　of　the　device　with　bare　TiO2　film.　Further　studies　confirm　that　the　grain　size　of　TiO2　with　La3+　doped　film　is　decreased　and　the　compactness　of　the　film　is　improved.　Besides,　La-doped　TiO2　film　shows　the　improved　morphology　and　optical　properties　leading　to　the　current　density　of　the　cells　increase　from　6.54　to　9.71 mA/cm2.　©　2016,　Springer　Science+Business　Media　New　York.
