New anthracene-thiophene-based copolymers that absorb across the entire UV-vis spectrum for application in organic solar cells.
We report a new class of anthracene-thiophene-based copolymers, PAT4. The UV-vis absorption spectrum of PAT4 was broad and covered the full range of the solar spectrum. The hole mobility of PAT4 was high, up to 0.037 cm(2) V(-1) s(-1). PAT4-based organic solar cells showed promising power conversion efficiencies of 1.7%.
