Electrical and thermal properties of a carbon nanotube/polycrystalline BiFeO3/Pt photovoltaic heterojunction with CdSe quantum dots sensitization
Electrical and thermal properties of a carbon nanotube (CNT)/multiferroic BiFeO 3 (BFO)/Pt photovoltaic heterojunction are investigated for the first time. Enhanced photovoltaic properties ( J sc 2.1 A cm 2 and V oc 0.47 V), as compared to the traditional polycrystalline BFO with indium tin oxide (I...
