Problems solved by technology

Limited by the laser power and spot size, the cutting speed and efficiency are difficult to meet the requirements of mass production. The opening size is small, and it is difficult to meet the larger light transmission requirements. If you want to make a larger light transmission opening, or the ratio of the light transmission opening area Larger light-transmitting thin-film solar cells will have high processing costs

Abstract

The invention discloses a light-permeable amorphous silicon film solar cell module and a manufacturing method thereof. The solar cell module comprises an insulated substrate; a first electrode layer, a p-i-n amorphous silicon film layer and a second electrode layer are arranged on one surface of the insulated substrate to form a film solar cell; a plurality of through holes used for light transmission are arranged on the insulated substrate; and the total area of the through holes takes up 5-30% of the area of the insulated substrate. As the through holes are formed on the insulated substrate, the first electrode layer, the p-i-n amorphous silicon film layer and the second electrode layer are deposited on the substrate to form the film solar cell. Compared with existing cell module, the invention does not use inefficient laser cutting technique to cut the light transmitting openings, thus improving the production efficiency and reducing the cost. The caliber, the shape and the arrangement mode of the light transmitting holes can be adjusted freely, thus satisfying the aesthetic requirements on the integration between curtain wall-like pv components and the buildings.

Description

technical field [0001] The invention relates to an amorphous silicon solar cell and a preparation method thereof, in particular to a light-permeable amorphous silicon thin-film solar cell module using an insulating material as a substrate and a manufacturing method thereof. Background technique [0002] Photovoltaic-building integrated solar cell modules as building components such as curtain walls generally require a light transmittance of 10 to 20%. Traditional solar cell modules of this type include amorphous silicon thin-film solar cell modules. In actual production, the battery modules are arranged intermittently. Light is transmitted through the gaps between the battery modules, and the light transmittance is adjusted by the size of the gaps. Such an arrangement is too plain to meet the requirements of architectural aesthetics. [0003] The general method of light-transmitting amorphous silicon thin-film solar cell module is to form thin-film solar cells on a transpar...
