摘要：
The effect of Mn-ion doping on the device performance of multilayer PbS quantum dot (QD) sensitized solar cells is investigated. Undoped as well as the doped PbS QDs, with different doping concentration, are synthesized using simple chemical methods on poly-vinyl alcohol matrix. QDs are characterized using ultraviolet visible spectroscopy, x-ray diffraction analysis, high-resolution transmission electron microscopy, energy dispersive x-ray, and photoluminescence spectroscopy. The QDs were introduced as sensitizer in ZnO-based solar cells in single as well as multiple layers. The current density vs. voltage characteristics are obtained for different Mn doping concentrations as well as for multiple numbers of QD layers, under artificial illumination. Enhanced photo-conversion efficiency was observed in multiple layered doped PbS QDs sensitized solar cell compared to undoped QDs sensitized solar cell.
