The Effect of Polymer Backbone Fluorination on the Light Utilization Efficiency of Truly Transparent Organic Photovoltaics

Transparent photovoltaics, a burgeoning field at the intersection of materials science and renewable energy technology, have the potential to revolutionize the way in which we harness sunlight and integrate solar power into our daily lives. The performance of transparent photovoltaics is evaluated by the light utilization efficiency and necessitates a trade-off between optimizing efficiency and ensuring transparency. In this work, a comparative analysis is performed of two donor polymer materials that differ only in the presence of a single fluorine atom among the polymer backbone, examining their performance in transparent solar cells in relation to both of these critical aspects.
