  • SEMITRANSPARENT PHOTOCONVERSION DEVICE
    Publication number: 20140318609
    Abstract: The main object of the present invention is to provide a semitransparent photo conversion device that enhances harvesting of visible sunlight. For this purpose, a semitransparent photovoltaic cell is provided with a multilayer structure that can be used to change the color hue appearance of the cell while guaranteeing a minimum change in the light absorption capability. The photo conversion device has a direct or inverted architecture that comprises a first light transmissive electrical contact overlaying a transparent substrate, a charge blocking layer overlying the first light transmissive electrical contact and underlying the active organic photosensitive material, a second charge blocking layer overlying the active organic photosensitive material, a second light transmissive electrical contact overlying the second charge blocking layer, and a multilayer structure overlying the second light transmissive electrical contact.
