NOVELTY - The device consists of an individually encapsulated solar cell consisting of protective layer coupled to a surface of the solar cell. The protective layer has chemical composition which prevents moisture from entering the solar cell. The light passes through the protective layer to reach an absorber layer in the solar cell. The protective layer comprises an inorganic material.    USE - For e.g. photovoltaic device used for solar cell and solar cell module.    ADVANTAGE - The device has excellent weather proof resistance, moisture protection property with respect to solar cell, and stability.
