Abstract

The invention discloses a solar cell module for a building roof. The solar cell module comprises a glass substrate, a first electrode plate, an amorphous silicon absorption layer, a silver film and anadhesive, wherein ZnO thin film is arranged at the lower portion the glass substrate, TiO2 thin film adheres to the lower portion of the ZnO thin film through the adhesive, SnO2 front electrode filmadheres to the lower portion of the TiO2 thin film through the adhesive, a front electrode plate is arranged at the lower portion of the SnO2 front electrode film and is arranged on the amorphous silicon absorption layer, a TCO film layer adheres to the lower portion of the amorphous silicon absorption layer through the adhesive, and silver film adheres to the lower portion of the TCO film layer through the adhesive. A semitransparent amorphous silicon film solar cell is high in performance, the absorbing capability of the amorphous silicon film is improved to the greatest degree, and the reflection reducing and transmission strengthening performance and sunlight utilization rate of the semitransparent amorphous silicon solar cell module are effectively improved.

Description

technical field [0001] The invention relates to the technical field of related equipment of solar cell components, in particular to a solar cell component used on the roof of a building. Background technique [0002] Building integrated photovoltaics is an important application field of solar power generation technology. Amorphous silicon thin film solar cells have broad development space in the field of building integrated photovoltaics due to their thin film characteristics, strong comprehensive power generation capacity, and beautiful appearance combined with glass. [0003] Please refer to figure 1 At present, aluminum and aluminum alloy films are used as the back electrode of amorphous silicon thin-film solar cells, which has poor light transmission performance and is not conducive to the application in the field of photovoltaic building integration. For this industry, lasers are usually used in thin-film solar cells The upper horizontal scribe line forms the light cha...
