  • TCO-based hybrid solar photovoltaic energy conversion apparatus
    Patent number: 8278549
    Abstract: The invention relates to a solar photovoltaic energy conversion apparatus. The apparatus consists of a substrate, a buffer layer formed on the substrate layer, a first transparent conductive oxide layer formed on the buffer layer, periodic protrusions containing first silicon layers formed on the first transparent conductive oxide layer, second silicon layers formed on the first silicon layers, a second transparent conductive oxide layer covering the first silicon layers, the second silicon layers and the first transparent conductive oxide layer, and an anti-reflective protective layer. The first silicon layer and the second silicon layer are the electrodes with the opposite type of charge carriers. The first transparent conductive layer and the second transparent conductive layer are the electrodes with the opposite type of charge carriers. This TCO-based hybrid solar photovoltaic energy conversion device not only can allow the transmission of visible sunlight but also can enhance the photovoltaic energy.
