Cartoon of the structure of the PTB7:PC71BM organic photovoltaic material without (a) and with (b) di-iodo-octane (DIO) additive. These cartoons illustrate conclusions derived from soft X-ray spectromicroscopy and resonant scattering studies (Collins et al., 2013BB18). (c) Cartoon of the exciton generation process at the interface of the two types of domains. [Adapted from Collins et al. (2013BB18), J.
