(ZH) 太阳能电池组件
Abstract
(EN)
The utility model provides a solar cell module. The solar cell module comprises a light-transmitting element, a front packaging layer, a plurality of solar cells which are arranged at intervals, a rear packaging layer and a packaging back plate which are sequentially arranged in the thickness direction of the solar cell module, the solar cell module also comprises a light guide film. The light guide film comprises a concave-convex reflective structure. The concave-convex light reflecting structure comprises a parallel triangular prism array; wherein the included angle between the orthographicprojection of the orientation direction of the parallel triangular prism array on the packaging back plate and the orthographic projection of the solar cell string on the packaging back plate is within the range of 45-80 degrees; and the vertical distance between the plane where each convex vertex of the concave-convex reflective structure is located and the plane where the solar cell is located is 200-600 [mu] m. According to the solar cell module of the utility model, high power generation efficiency can be realized under the condition that safety is satisfied.
