XUSolarconcentratingphotovoltaictechnologyhastheadvantagesofhighconcentration ratio，suchaslessbattery material consumption， high photoelectric conversion efficiency. In this paper， the working principle of the solar concentrating photovoltaic and the latest research progress of the photovoltaic concentrators in recent years are presented. The concentrating theory，design methods and performance characteristics of the different photovoltaic concentrators are analyzed and summarized. By using the secondary concentrator and the optical waveguide，the higher concentration ratio and moreuniformfluxdistribution isobtained. Thephotoelectric conversion efficiencyisimproved. Thepolymer materials isusedintheconcentrator，sothatthecostofthelensandwaveguidecanbereduced.Themethodsofmoldingandinjection moldingareusedinprocessingoftheconcentrator.Itisnotonlytobeneficialtoreducethecostoftheconcentrator，achieve mass production，but also is better to control the production quality. With the reduction of the cost of photovoltaic concentrator，theimprovementoftheconcentratingperformanceandthedevelopmentofmultijunctionsolarcells，thesolar concentratingphotovoltaictechnologywillbewidelyused.
