Unraveling Device Physics of Dilute‐Donor Narrow‐Bandgap Organic Solar Cells with Highly Transparent Active Layers (Adv. Mater. 31/2022)

Photoactive Materials Next-generation photovoltaics will be lightweight, flexible, and (semi)transparent. Highly transparent organic photoactive materials are reported by Thuc-Quyen Nguyen, Viktor Brus, and co-workers in article number 2203796. The changes in the fundamental processes in solar cells comprising a near-IR-absorbing acceptor and a visible-light-absorbing donor are revealed upon dilution of the donor material, paving the way for integrated energy-harvesting solutions based on semitransparent organic photovoltaics.
