Abstract
NiO and Cu:NiO powder prepared by sol-gel method and solution treatment was spin-coated on CdTe layer to form Cu:NiO back contact of CdTe solar cell. The performances of the solar cell with CdS/CdTe/Cu:NiO structure were simulated and analyzed using AMPS software. Through the simulations, we investigated the effect of the back contact layer thickness and carrier concentration on the solar cell performances. The maximum efficiency of 19.26% was obtained at the back contact layer thickness of 20 nm and carrier concentration of 1018 cm–3. And we carried out the measurement of the recombination resistance and solar cell performances with different copper doping concentration for Cu:NiO back contact. The maximum efficiency was obtained at 5% copper doping concentration.
期刊介绍：
Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
