| Outline of Final Research Achievements |
In this research, we have developed a "see-through organic solar cell panel" with a controlled absorption wavelength range. The purpose of this study is to realize a new solar panel that transmits necessary light for agriculture or house-use while absorbing the remaining light for generating electricity. As a result of this research, in terms of materials, we have developed squaraine-based organic solar cell materials (conversion efficiency up to 7%) absorbing the target from 500 nm to 600 nm (green light) or 700 nm to 800 nm (deep red to near infrared light). We have also realized multicolor semitransparent organic solar cells (average light transmittance: 10% to 30%, conversion efficiency up to 5%) using these materials. "See-through organic solar cell panels" were exhibited at the JFlex and PV EXPO exhibitions.
