WebThiophene dendrimer spin-coated films were fabricated and the optical and photoelectric properties were investigated. Absorption edge and peak of photoluminescence (PL) spectra for the film were observed at around 550 and 618 nm, respectively. The excitation spectrum almost corresponded with optical absorption. WebDec 21, 2016 · Compared to thiophene dendrimer D1, D4 showed a broad absorption band covering 300–700 nm and a reduced bandgap of 1.7 eV. In BHJ solar cells, low-bandgap dendrimer D4 gave a PCE of 1.3 % in combination with PC 61 BM as acceptor, whereas a PCE of 1.0 % was obtained with all-thiophene dendrimer D1 (R=SiMe 3).
