2012 (English)In: Tetrahedron Letters, ISSN 0040-4039, E-ISSN 1873-3581, Vol. 53, no 27, 3425-3428 p.Article in journal (Refereed) Published
Four organic donor-Ï€-conjugated-acceptor (D-Ï€-A) type II dyes with different thiophene linkers are reported for dye sensitized solar cells (DSSCs). For the first time, a donor (triphenylamine) was introduced in type II sensitizers, and 2-hydroxybenzonitrile as acceptor/anchoring moiety was covalently linked TiO 2 particles. The dye LS203 in this series gives the best solar energy conversion efficiency of 3.4%, with J sc = 7.4 mA cm -2, V oc = 0.67 V, FF = 0.69, the maximum IPCE value reaches 66.9%.
