Abstract
Organic solar cells (OSC) have attracted significant interest as promising candidates for renewable energy, due to the advantages of flexibility, light weight, and low-cost production. Performance of bulk heterojunction (BHJ) devices made from mixtures of polymer and fullerene are very sensitive to the nanoscale morphology in the blends. That encourages people to control processing conditions to optimize morphology and hence to improve device performance. Simultaneous measurement of structure and property on each sample is needed because of poor repeatability of OSCs. We built and classified our customized solar simulator to realize the all in-situ characterization. In this approach, we were able to perform all the structure and property measurements without encapsulating the devices. Therefore, device performance is better correlated to the corresponding structure. That helped us understand the role of the morphologies in the efficiency enhancement of annealed organic photovoltaics.
