  • Thin film solar cell structure and fabricating method thereof
    Publication number: 20120024366
    Abstract: A thin film solar cell structure and the fabricating method thereof are disclosed. A passivation layer is embedded into the thin film solar cell structure to be in contact with an absorbing layer. The interface trap density of the absorbing layer is reduced by the surface electric field of the passivation layer. The invention helps improve the power conversion efficiency and protect the absorbing layer.
