NOVELTY - Apparatus comprises: a solar cell; a transparent covering; and an eutectic interlayer that binds the solar cell and the transparent covering together, where at least some of a compound of the eutectic interlayer is bonded with the transparent covering, raising the melting temperature of the eutectic interlayer above the melting temperature with the full amount of the compound present.    USE - The apparatus is useful for: bonding a solar cell to a transparent covering using a eutectic interlayer; and creating a transparent cell covering using a eutectic layer without a separate transparent covering (all claimed).    ADVANTAGE - The apparatus utilizes eutectic interlayer materials which: do not become contamination source when utilized in concentrator applications under sustained high temperature exposure; and do not experience dramatic changes in mechanical compliance at low temperatures.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) bonding (M1) a solar cell to a transparent covering using a eutectic interlayer, comprising placing a eutectic layer in a solid or liquid state in contact or close proximity to a solar cell, heating the eutectic layer to a sufficiently high temperature to transition to a liquid state, where the liquid eutectic layer wets a surface of the solar cell, covering surface components of the solar cell, and modifying a chemistry of the eutectic layer so that the eutectic layer solidifies on the surface of the solar cell, forming a transparent layer; and    (2) creating a transparent cell covering using a eutectic layer without a separate transparent covering (1200), comprising placing a eutectic layer in contact or close proximity to a solar cell (1210), heating a process chamber (1220), increasing a concentration of a gas in the process chamber (1230) that causes the eutectic layer to transition into a liquid state so that the eutectic layer coats a surface of the solar cell, and lowering the concentration of the gas (1240) so that the eutectic layer solidifies on the surface of the solar cell, forming a transparent covering.    DESCRIPTION OF DRAWING(S) - The figure shows a flowchart of the method for creating the transparent cell covering using a eutectic layer without a separate transparent covering.
