Assistant Professor Viktor Brus from NU SSH and international co-workers reported highly transparent organic photoactive materials and published “Unraveling Device Physics of Dilute-Donor Narrow-Bandgap Organic Solar Cells with Highly Transparent Active Layers” in Advanced Materials volume 34, issue 31.
They claim that next-generation photovoltaics will be lightweight, flexible, and (semi)transparent. 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.
The picture was made by Viktor Brus, Assistant Professor, Department of Physics.
