Solar battery module and manufacturing method thereof

Abstract

The invention discloses a solar battery module includes a substrate, a plurality of first striped electrodes separately formed on the substrate, a plurality of striped photoelectric transducing layers respectively formed on the corresponding first striped electrode and the substrate wherein parts of the first striped electrode are exposed, a plurality of second striped electrodes respectively formed on the corresponding striped photoelectric transducing layer, and a plurality of conductive layers respectively formed on a side of the corresponding second striped electrode and the first striped electrode adjacent to the side, and not contacting the other second striped electrode. The solar battery module and the related manufacturing method of the present invention can economize the machine cost, increase the speed of the procedures, and reduce the proportion of the inactive area to the panel dimension of the solar battery module, so as to enhance the photoelectric transducing efficiency of the solar battery module.

Description

technical field [0001] The present invention relates to a solar cell module and a manufacturing method thereof, in particular to a solar cell module with a small proportion of ineffective areas to have optimal photoelectric conversion efficiency and a manufacturing method thereof. Background technique [0002] Traditional solar cell modules go through several cutting steps, generally three cutting steps are required to remove the first electrode layer, the photoelectric conversion layer and the second electrode layer respectively to form a solar cell with a plurality of battery cells connected in series module. On the solar cell module, the section after the cutting step is called an invalid area because it cannot perform photoelectric conversion. The width of the invalid area formed by the process of the traditional solar cell module is about 0.5mm, and the invalid area will reduce the photoelectric conversion efficiency of the solar cell module. For example, US Pat. No. ...

AI Technical Summary

Problems solved by technology

However, the conventional process needs to further perform a cutting step after forming the conductive layer to remove part of the second electrode layer adjacent to the conductive layer, so as to prevent the electrode layer from contacting the first electrode layer of any battery cell at the same time. The electrode layer and the second electrode layer are short-circuited, so the cutting steps of the process are cumbersome, consume more man-hours, and greatly increase the area of ​​the ineffective region, which cannot effectively and stably improve the photoelectric conversion efficiency of the solar cell module
