Translucent type thin-film solar cell module and manufacturing method thereof

Abstract

The invention provides a transparent thin-film solar battery module and manufacture method thereof. The manufacture method forms openings in two directions in a transparent eletrode material layer, thus avoiding a negative influence on the process yield rate due to the problem of short circuit caused by the laser cutting process at a high temperature. Additionally, the transparent thin-film solar battery module has the openings exposing a transparent substrate without covered transparent electrodes, thus improving the light transmittance of the battery.

Description

technical field [0001] The present invention relates to a photovoltaic (photovoltaic) module and its manufacturing method, and in particular to a light-transmitting thin-film solar cell module and its manufacturing method. Background technique [0002] Solar energy is an energy source that is inexhaustible and non-polluting. It has always been the focus of attention when solving the problems of pollution and shortage of petrochemical energy. Among them, a solar cell can directly convert solar energy into electrical energy, and has become a very important research topic at present. [0003] At present, in the solar cell market, cells using monocrystalline silicon and polycrystalline silicon account for more than 90%. However, these solar cells need to use silicon wafers with a thickness of about 150 micrometers to 350 micrometers as materials, and the cost is relatively high. Furthermore, since high-quality silicon crystal ingots are used as raw materials for solar cells, d...

Problems solved by technology

However, this patent needs to use the yellow light process, and its related equipment is quite expensive, which will increase the cost

Moreover, if this patent uses laser cutting to directly form the hole 6, it will also cause metal particle pollution and short circuit problems, which will affect the process yield.
