The Effect of Processing Additives on Energetic Disorder in Highly Efficient Organic Photovoltaics: A Case Study on PBDTTT‐C‐T:PC71BM. (27th May 2015) - Gao, Feng
Abstract Energetic disorder, an important parameter affecting the performance of organic photovoltaics, is significantly decreased upon the addition of processing additives in a highly efficient benzodithiophene‐based copolymer blend (PBDTTT‐C‐T:PC71BM). Wide‐angle and small‐angle X‐ray scattering measurements suggest that the origin of this reduced energetic disorder is due to increased aggregation and a larger average fullerene domain size together with purer phases.
