Lidzey Solar Cells: Correlating Structure with Function in Thermally Annealed PCDTBT:PC70BM Photovoltaic Blends (Adv. Funct. Mater. 7/2012) Advanced Functional Materials 22
On page 1399, Tao Wang, David G. Lidzey, and co-workers characterize the nanostructure of poly -[N-9′-heptadecanyl-2,7-carbazole-alt-5,5-(4′,7′-di-2-thienyl-2′,1′,3′-benzothiadiazole) (PCDTBT):(6,6)-phenyl C70-butyric acid methyl ester (PC70BM) bulk heterojunction (BHJ) solar cells upon thermal annealing using a optical probes including grazing incidence wide-angle X-ray scattering, spectroscopic ellipsometry, and pho-toluminescence spectroscopy. The measurements allow the film nanostructure to be correlated with both charge-carrier mobility and the performance of a photo-voltaic device.
