EurekAlert June 23, 2021 Although the organic photovoltaic (OPV) elements are lighter, more flexible, and cheaper to produce, their efficiency still falls behind that of other photovoltaic technologies. An international team of researchers (Saudi Arabia, Lithuania, Greece) synthesised a material, which self-assembles into a monolayer that can cover a variety of surfaces and function as a hole-transporting layer in a solar element. They made some modifications in the material used in self-assembling molecular-thin layer (SAM) formation to tailor it for organic solar elements. The organic solar cell using Br-2PACz molecule-thin coating as a hole-transporting layer achieved a power conversion efficiency […]

Welcome indoors, solar cells
Eurekalert September 16, 2019 An international team of researchers (China, Sweden) developed a new combination of donor and acceptor materials, with a carefully determined composition, to be used as the active layer in an organic solar cell. The power they produce is low but is probably enough to feed the millions of products IoT products. They designed a non-fullerene acceptor named IO-4Cl and blend it with a polymer donor named PBDB-TF to obtain a photoactive layer whose absorption spectrum matches that of indoor light sources. The photovoltaic characterizations reveal a low energy loss below 0.60 eV. As a result, the organic […]
