No. 62/538,405 filed Jul. 28, 2017, entitled “A 1,2,5,6-Naphthalenediimide Co-Polymer”, which is hereby incorporated by reference in its entirety.None.This invention relates to high performance wide-bandgap polymers for organic photovoltaics.Solar energy using photovoltaics requires active semiconducting materials to convert light into electricity. Currently, solar cells based on silicon are the dominating technology due to their high-power conversion efficiency. Recently, solar cells based on organic materials showed interesting features, especially on the potential of low cost in materials and processing.Organic photovoltaic cells have many potential advantages when compared to traditional silicon-based devices. Organic photovoltaic cells are light weight, economical in the materials used, and can be deposited on low cost substrates, such as flexible plastic foils. However, organic photovoltaic devices typically have relatively low power conversion efficiency (the ratio of incident photons to energy generated). This is, in part, thought to be due to the morphology of the active layer. The charge carriers generated must ...
