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.

Embodiment Construction

[0044] Figure 4a to Figure 9c It is a schematic flowchart of a manufacturing method of a light-transmissive thin-film solar cell module according to an embodiment of the present invention. in, Figure 4a , 5a , 6a, 7a, 8a, 9a are diagrams showing the top view, Figure 4b , 5b , 6b, 7b, 8b, 9b, 9b' are schematic cross-sectional views along the section line I-I', Figure 9c is a schematic cross-sectional view along the section line II-II'.

[0045] First, please refer to Figure 9a , Figure 9b , Figure 9b 'and Figure 9c , the light-transmissive thin-film solar cell module 400 of this embodiment is composed of a plurality of cells (cells) 401 connected in series. Moreover, a plurality of X-direction openings 422 and Y-direction openings 420 of the transparent substrate 402 are exposed between the cells 401 . Therefore, when light (sunlight) irradiates from the bottom of the transparent substrate 402 , it can pass through the X-direction opening 422 and the Y-directio...

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...
