AI Technical Summary

Technical Problem

Existing solar cell modules face challenges in achieving three-dimensional image expression with a small number of printing layers, require complex color matching and registration during printing, and suffer from reduced power generation efficiency due to excessive sunlight blocking by printed matter.

Method used

A solar cell module design featuring a translucent substrate with a first-color pattern layer and a second-color pattern layer, each containing interference pigments that generate different interference lights, allowing for three-dimensional pattern expression with simplified color matching and registration, and ensuring sunlight transmission to maintain power generation efficiency.

Benefits of technology

The design enables three-dimensional image expression with a reduced number of printed layers, simplifies color matching and registration, and suppresses a decrease in power generation efficiency by allowing sunlight transmission.

Abstract

To provide a solar cell module which can express a pattern with a three-dimensional effect even if the number of print layers is small, and comprises a print material having a designability which enables a simplification of a color matching operation at a print and a registration work and an excellent power generation efficiency.SOLUTION: A print material 2 comprises: a first color pattern layer 10 constructed by a plurality of first color dots 11; and a second color pattern layer 20 that is constructed by a plurality of second color dots 21. Each first color dot 11 contains: a first color binder 12; and a plurality of first color pigment chips 13 that is scattered into a binder inner part. Each second color dot 21 contains: a second color binder 22; and a plurality of second color pigment chips 23 that is scattered into an inner part of the binder. The plurality of first color pigment chips 13 are a plurality of colors of first interference pigment chips 14a and 14b that generate first interference lights 15a and 15b that are different each other. The plurality of second color pigment chips 23 are second interference pigment chips 24 that generate a second interference light 25 of a single color that is different from a mix color indicated by each of the first interference pigment chips 14a and 14b.SELECTED DRAWING: Figure 3
