Benefits of technology

The solution enables continuous, efficient resin-sealing of solar cells with improved weather resistance and durability, reducing maintenance and contamination risks, and simplifying the apparatus constitution, while maintaining excellent exterior appearance and performance.

Problems solved by technology

However, these solar cell production processes using such lamination have disadvantages such that a plurality of lamination materials are necessary to be used and a large investment in plant and equipment is required, and therefore, the resulting solar cell unavoidably becomes costly, and this results in a raise in the power generation cost of the solar cell.
However, any of the resin-sealing methods has such disadvantages as will be described in the following.
This makes the apparatus complicated, and an extra investment therefor is necessitated.
When the resin sealing of the photovoltaic element is continuously performed while disregarding the incidence in that the conveyor belt is stained, the yield of a product is disadvantageously decreased.

example 1

1. Preparation of Photovoltaic Element:

[0095] An amorphous silicon (a-Si) photovoltaic element having such configuration as shown in FIGS. 1(a) and 1(b) with no resin layer 107 was prepared in the following manner.

[0096] There was provided a well-cleaned stainless web substrate having a thickness of 150 μm and a width of 355 mm as the substrate 101. On the web substrate, there was formed a two-layered back reflecting layer 102 comprising a 5000 Å thick Al film / a 5000 Å thick ZnO film by means of the conventional roll-to-roll sputtering process.

[0097] On the back reflecting layer 102 thus formed, there was formed a tandem type photoelectric conversion semiconductor layer as the semiconductor active layer 103 comprising a 150 Å thick n-type amorphous silicon layer / a 4000 Å thick i-type amorphous silicon layer / a 100 Å thick p-type microcrystalline silicon layer / a 100 Å thick n-type amorphous silicon layer / a 800 Å thick i-type amorphous silicon layer / a 100 Å thick p-type microcrysta...

example 2

[0126] The procedures of Example 1 were repeated, except that a curtain coater was used as the spouting means and the spouting width of the resin layer precursor to get down on the surface of the photovoltaic element was made to be 300 mm, to obtain three photovoltaic elements having a resin-sealed structure.

[0127] The resultant three photovoltaic elements were evaluated in the same manner as in Example 1. The evaluated results are shown in Table 1.

Abstract

A coating apparatus process for producing a coating resin layer on a substrate includes a fastening table for fastening the substrate and a spout for spouting a resin layer precursor onto the substrate.

Description

[0001] This application is a divisional of application Ser. No. 10 / 323,893, filed Dec. 20, 2002, now U.S. Pat. No. 6,953,599.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a process and an apparatus for producing a substrate having a coating resin layer which excels in the weather resistance and durability and which also excels in productivity. [0004] 2. Related Background Art [0005] In the case where a substrate such as a plastic plate, a steel plate or a galvanized steel plate is used outdoors, there is often adopted such a manner that prior to using said substrate, decorative coating is performed so that the substrate has improved weather resistance and improved durability. In this case, for instance, when the substrate is a steel plate or a galvanized steel plate, it is important that a coating material which is satisfactory in terms of the weather resistance and the durability is used for the decorative coating and the inter...
