The two types of material used are electron donor and acceptor material
, forming an interface wherein photo-induced electron transfer (PET) can occur from to donor to acceptor under visible light irradiation," Zang explained.
The introduction of a new acceptor material
allows for the application of new classes of organic materials as photoactive layers to improve the conversion efficiency.
The absorber material, in essence, releases the electron to the acceptor material.
They also typically use fullerenes as the acceptor material due to its high electron mobility and inherent talent for accepting stable electrons.
oThis dark shadow state can be the most efficient source of two electrons via transfer to an electron acceptor material
, such as fullerene, which was used in the study.
The paper titled "Endohedral fullerenes for organic photovoltaic devices" presents a unique approach to enhance flexible, plastic solar cells, also known as organic photovoltaic (OPV) cells, by modifying the acceptor material rather than the donor material.
Luna's novel acceptor materials operate at high conversion efficiencies and are an excellent complement to the fast growing semi-conductive-polymer field.
Herein, we report our efforts in exploring a new class of molecular acceptor materials
based on a well-known organic pigment core of quinacridone.
We will show patterned thin films of organic photovoltaics relevant materials, including conductive silver used in cathodes, carbon nanotubes used as transparent conductors, conjugated polymers used in the active layer and quantum dots, band gap acceptor materials
that also function in non-white lights environments.
Book offers a comprehensive treatment of nonhybrid polymeric solar cells from the basic chemistry of donor and acceptor materials
through device design, processing and manufacture.
Firstly, the implementation of fullerene-free acceptor materials
resulted in high open-circuit voltages and useful absorption spectra in the visible.
Merck s PV-D donor polymer materials and PV-A fullerene derivative acceptor materials
are production-ready owing to their high conversion efficiencies and high solubility in non-halogenated solvent systems, enabling cost-effective green production technologies.
