HIGH CONCENTRATED PHOTOVOLTAIC (HCPV) SOLAR CELL MODULE

摘要

A high concentrated photovoltaic (HCPV) solar cell module, comprising: a set of Fresnel lenses, a Group III-V semiconductor solar cell, and a substrate used to carry said Group III-V semiconductor solar cell. Wherein, said substrate is made of material of good heat dissipation, for assisting heat dissipation. Said set of Fresnel lenses includes a plurality of stacked-up Fresnel lenses, thus concentrating sunlights to said Group III-V semiconductor solar cell with a significantly higher concentration ratio. As such, in addition to the advantages of small volume, light weight, and cost saving, it is devoid of the problem of a conventional single piece Fresnel lens of insufficient light concentration capability. Therefore, said Group III-V semiconductor solar cell is capable of receiving much more sunlights per unit area, and achieving high photoelectric conversion efficiency; meanwhile, reducing number and area required by said Group III-V semiconductor solar cell, thus achieving reduction of production cost.
