Title:
ジフルオロベンゾトリアゾリル太陽電池材料、調合法、およびその使用方法
Document Type and Number:
Japanese Patent JP5701453
Kind Code:
B2
Abstract:
The present invention relates to solar cells and discloses a difluoro benzotriazolyl solar cell material and preparation method and use thereof. The solar cell material is represented by formula (I),
wherein both R 1 and R 2 are C 1 to C 20 alkyl, and n is an integer from 10 to 50. In the difluoro benzotriazolyl solar cell material, since the 1, 2, 3-benzotriazole solar cell material contains two fluorine atoms, the HOMO energy level is reduced by 0.11eV, while the fluorine-substituted 1, 2, 3-benzotriazole has two imido groups with electron-withdrawing ability; the fluorine-substituted 1, 2, 3-benzotriazole is a heterocyclic compound with strong electron-withdrawing ability, and an alkyl chain can be easily introduced to the N-position of the N-H bond of the benzotriazole. The functional group of the alkyl chain can improve the solar energy conversion efficiency, thus solving the low efficiency problem of solar cells made of the solar cell material.
