In　concentrating　photovoltaic　module,　employment　of　secondary　optics　can　be　effective　in　increasing　the　acceptance　angle　and　incident　light,　as　well　as　improving　the　energy　uniformity　of　focal　spot.　A　design　of　reflective　secondary　optics　for　concentrating　photovoltaic　module　is　presented.　The　3D　model　of　this　design　is　established　by　Solidworks　software　and　important　parameters　such　as　inclination　angle　and　component　height　get　optimized　using　Zemax　software.　According　to　the　design　and　simulation　results,　several　secondary　glass　prisms　with　different　parameters　are　fabricated　and　tested　in　combination　with　Fresnel　lens　and　multi-junction　solar　cell.　The　sun-simulator　I-V　test　results　show　that　the　combination　has　the　highest　output　power　when　secondary　optics　height　is　6mm　and　upper　circle　diameter　is　7　mm.　The　output　power　can　reach　720　mW,　which　improves　16%　compare　to　without　secondary　optics.　It　shows　that　secondary　optics　is　very　important　in　concentrating　photovoltaic　module.　©,　2015,　Chinese　Optical　Society.　All　right　reserved.
