  • 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 ...

  • For cheaper solar photovoltaic systems

    It is known for several decades, photovoltaic devices that exploit the sun's energy to convert into electricity used to provide a sustainable alternative - and potentially unlimited - the use of fossil fuels. So why these solar technologies have they not been adopted more widely? Simply “because they are too expensive," said Ji-Seon Kim, professor of Solid Physics at Imperial College of ...

  • Spi-Sun simulator sets the standard

    Solar Simulators are critical to the industry testing photovoltaic modules featuring light sources that closely match the solar spectrum. Spire’s simulators can test the full range of solar modules – including crystalline or thin film. The importance of solar simulation is clear – solar modules must be tested under a standard set of conditions to assure consistency of results. ...

  • 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 ...
