NOVELTY - An apparatus comprises a direct or indirect photon converter or producer and electrical connection apparatus having repetitively shaped granular semiconductor (65) bodies, repetitively formed slot, hole, slots, or holes to hold the semiconductor bodies, light conduit to the semiconductor body or bodies, and at least two electrodes that are part of the slot or hole that with elastic compression touch each semiconductor body.    USE - As a photovoltaic cell, light emitter, thermal energy to electric converter or refrigerator (claimed).    ADVANTAGE - The apparatus with high performance characteristics, precision dimensions, and low cost; with small dimensional optics, small photovoltaic cells have heat distribution surfaces, very high concentrations and subsequently high utilization of the semiconductors is achieved.    DETAILED DESCRIPTION - An apparatus comprises a direct or indirect photon converter or producer and electrical connection apparatus having repetitively shaped granular semiconductor (65) bodies, repetitively formed slot, hole, slots, or holes to hold the semiconductor bodies, light conduit to the semiconductor body or bodies, and at least two electrodes that are part of the slot or hole that with elastic compression touch each semiconductor body. The light conduit further comprises mirrors, lenses, transparent materials, scintillators, phosphors, scattering surfaces, diffractive, or interference structures which concentrate light to the photon converters. The apparatus further comprises a non-flat light transparent refractive cover shaped to fit over the shaped semiconductor bodies and concentrate light to the semiconductor bodies, and where the bodies that are electrically connected form an array of photovoltaic cells; an electrical connection which is also a light collection system of either a light reflector, refractive reflector, scatterer, scintillator, or phosphor; radiant emission or convection enhancing heat transfer structure or material coating on one outer surface of the contacts; sticky surface be located within the formed slot or hole and used to hold the shaped semiconductors within the shaped slots or holes or as a temporary holding surface.
