Photostable donor–acceptor–donor fluorophores, which have a central quinoxaline acceptor nucleus, been used in LSCs, obtaining outstanding results for modern building-integrated photovoltaics (BIPV).

Transient absorption and time-resolved fluorescence measurements in a wide temperature range are used to investigate the mechanism of charge carrier generation efficient organic solar cells based on PM6:Y6 donor–acceptor blend. The mechanisms differ significantly under excitation donor or acceptor. investigations reveal temperature-dependent interplay between formation interfacial transfer (CT)...

Asymmetrically functionalized single-wall carbon nanotubes (SWNTs) have been prepared by a covalent reaction of an 11-mercaptoundecanol-modified Au surface with oxidized SWNT cylinders. While one end of the tubes is attached to gold substrate via ester groups, the free carboxylic substituents on the other end can be either ionized (CO2-) or esterified (CO2Et), creating a donor-acceptor asymmetr...

Solar cells based on p-conjugated donor-acceptor (D-A) organic molecular systems are a promising alternative to conventional electrical energy generation. D-A systems, which have triphenylamine (TPA) moiety linked with benzothiadiazole (BTD) moiety, open the potential development of new small molecule donors for bulk heterojunction (BHJ) solar cells. Here, series donor-acceptor-π-acceptor (D-A-...

Förster resonance energy transfer (FRET) interacted with localized surface plasmon (LSP) gives us the ability to overcome inadequate transfer of energy between donor and acceptor nanocrystals (NCs). In this paper, we show LSP-enhanced FRET in colloidal photosensors of NCs in operation, resulting in substantially enhanced photosensitivity. The proposed photosensitive device is a layered self-ass...
