NOVELTY - The apparatus such as receiver package comprises a lead-frame comprising first and second conductive elements (435, 440), a solar cell comprising an active area and electrically coupled to the first conductive element, a mold compound (455) disposed on the lead-frame and the solar cell and forming a first aperture (461) with a wall around a portion of the active area and a second aperture (466) around a portion of the first conductive element, and an optical element disposed in the first aperture. The wall of the first aperture comprises a reflective surface.    USE - Used as an apparatus such as receiver package.    ADVANTAGE - The apparatus exhibits improved electrical insulation thus resulting in better performance during a high potential electrical withstand test and better protection against environmental conditions in a concentrated photovoltaic system, reduces manufacturing costs of the solar energy cell by minimizing the number of parts in the overall receiver design, and improves operational lifetime, alignment, power generation efficiency, power dissipation and electrical isolation of the solar energy cell.    DETAILED DESCRIPTION - The apparatus such as receiver package comprises a lead-frame comprising first and second conductive elements (435, 440), a solar cell comprising an active area and electrically coupled to the first conductive element, a mold compound (455) disposed on the lead-frame and the solar cell and forming a first aperture (461) with a wall around a portion of the active area and a second aperture (466) around a portion of the first conductive element, and an optical element disposed in the first aperture. The wall of the first aperture comprises a reflective surface, which is applied onto the first aperture. The optical element is co-molded in the first aperture. The portion of the first conductive element protrudes into the second aperture, and comprises an electrical connector. An insulator is disposed in the second aperture and surrounds the portion of the first conductive element. The second conductive element is electrically isolated from the first conductive element. The solar cell comprises a first conductive terminal disposed on a same side of the solar cell as the active area and exhibiting a first polarity, and a second conductive terminal disposed on an opposite side of the solar cell as the active area and exhibiting a second polarity. The first conductive terminal is electrically coupled to the first conductive element. The mold compound defines a third aperture over a portion of the second conductive element and on the same side of the lead-frame as the first and second apertures. The mold compound is a polymer e.g. white silicone or ceramic particles e.g. silica. An INDEPENDENT CLAIM is included for a method for fabricating a lead-frame receiver package.
