Problems solved by technology

However, in the manufacturing process, a short circuit is caused due to misalignment; the size of the components on the left and right sides is affected by the alignment factor of the transparent layer 14, which is different from other normal components, which affects its electrical properties; and the effective area of ​​the solar panel Due to the limited capacity of each machine, the size is often limited by 4mm to 8mm due to the shadow effect caused by misalignment.

Abstract

The invention provides a thin film solar battery structure and a manufacturing method thereof. An effective area of a solar panel is defined by a laser abrasion method and a mechanical abrasion method during manufacturing, so that an aim of enlarging the effective area of the solar panel can be fulfilled by a non-aligning mode.

Description

technical field [0001] The invention relates to a solar cell structure and a manufacturing method thereof, in particular to a structure with an enlarged effective area of ​​a solar panel and a manufacturing method thereof. Background technique [0002] A solar cell is a photovoltaic device that converts light energy directly into electrical energy. The most common solar cell material is silicon, which is in the form of mono- or polycrystalline wafers. However, the electricity generated by silicon-based solar cells is more expensive than electricity generated by more traditional methods. Therefore, efforts were made in the early 1970's to reduce the cost of solar cells. One way to reduce the cost of solar cells is to develop low cost thin film growth techniques that can deposit solar cell mass absorber materials on large area substrates and use high throughput low cost methods to manufacture solar cells.
