Effect of trap depth and interfacial energy barrier on charge transport in inverted organic solar cells employing nanostructured ZnO as electron buffer layer
Inverted organic solar cells with device structure ITO/ZnO/poly (3–hexylthiophene) (P3HT):[6,6]–phenyl C61 butyric acid methyl ester (PCBM)/MoO3/Ag were fabricated employing low temperature solution processed ZnO as electron selective layer. Devices with varying film thickness of ZnO interlayer were investigated. The optimum film thickness was determined from photovoltaic parameters obtained from ...

Quantum dots of lead selenide: evolution of size and geometry and influence on photovoltaic effect
Lead selenide quantum dots were synthesised by the colloidal chemical synthesis route at different reaction temperatures. The nanocrystals were characterised by X–ray diffraction (XRD), High–resolution transmission electron microscopy (HRTEM) and FTIR spectroscopy. Diameter of the PbSe quantum dots increased with reaction temperature, with average diameter varying from 30 nm to 200 nm at reaction ...
