Bonding of photovoltaic device to covering material

摘要

A solar energy collection system includes a solar cell, a transparent covering, and a eutectic interlayer binding the solar cell and the transparent covering together. At least some of a compound of the eutectic interlayer bonds with the transparent covering, raising the melting temperature of the eutectic interlayer above the melting temperature with the full amount of the compound present.

主权项

1. A method, comprising:
placing a eutectic layer in a solid or liquid state in contact with or close proximity to a solar cell; when in a solid state, heating the eutectic layer to a sufficiently high temperature to transition to a liquid state; wetting a surface of the solar cell with the liquid eutectic layer, forming an interlayer that covers surface components of the solar cell; contacting a transparent covering to the interlayer; and modifying a chemistry of the interlayer such that the interlayer solidifies on the surface of the solar cell, forming a transparent layer between the transparent covering and the solar cell.
