NOVELTY - The method comprises coupling an optical concentrating element having first and second sides of a second substrate member to a surface region of photovoltaic strips (105) such that a liquid optical elastomer material having a first thickness is placed in between the surface region of photovoltaic strips of a lead frame member and a second side of the optical concentrating element to form a first interface within a vicinity of the surface region and the thickness of the optical elastomer material and a second interface within a vicinity of the second side and the optical elastomer material.    USE - The method is useful for fabricating a solar cell, which is free and separate from a solar panel.    ADVANTAGE - The method is capable of economically and efficiently fabricating the easy to handle solar cell with light weight and improved reliability and quality in less consumption of energy.    DETAILED DESCRIPTION - The method comprises coupling an optical concentrating element having first and second sides of a second substrate member to a surface region of photovoltaic strips (105) such that a liquid optical elastomer material having a first thickness is placed in between the surface region of photovoltaic strips of a lead frame member and a second side of the optical concentrating element to form a first interface within a vicinity of the surface region and the thickness of the optical elastomer material and a second interface within a vicinity of the second side and the optical elastomer material, maintaining a spacing between the second side of the optical concentrating element and the surface region of the photovoltaic strip using particles having a predetermined dimension spatially disposed overlying the surface region of the photovoltaic strip and within a second thickness of the optical elastomer material, ultraviolet and thermally curing the optical elastomer material between the surface region and the second side, providing the first and second interfaces free from gaps to form a continuous optical interface from a first side of the optical concentrating element through the first and second interfaces to the photovoltaic strip, and providing a backside housing on the lead frame member. The photovoltaic strip has a back side region, which is provided on the lead frame member, and comprises a silicon bearing material. The optical elastomer material comprises a film of material, and a tape material. The photovoltaic strip is bonded to a first substrate using a solder paste material. The concentrating element comprises a thickness of material between the first side and the second side. A first substrate member comprises a copper material or an Alloy 42 material. The first interface is free from a bubble within the gaps. The particles comprise spherical glass beads, and are embedded in the optical elastomer material. An INDEPENDENT CLAIM is included for a solar cell device.    DESCRIPTION OF DRAWING(S) - The diagram shows an expanded view of a solar cell structure.
