Abstract Thermally induced degradation of organic photovoltaic devices hinders the commercialization this emerging PV technology. Thus, a precise understanding origin thermal device instability, as well identifying strategies to circumvent is utmost importance. Here, it investigates thermally‐induced state‐of‐the‐art PBDB‐T‐2F (PM6):BTP (Y6) bulk heterojunction solar cells at different temperatures and reveal changes their optical properties, photophysics, morphology. The open‐circuit...
Abstract Thermal annealing alters the morphology of organic donor-acceptor bulk-heterojunction thin films used in solar cells. Here, we studied influence thermal on blends amorphous regio-random (RRa) and semi-crystalline regio-regular (RR) poly (3-hexylthiophene) (P3HT) fullerene derivative [6,6]-phenyl-C 60 -butyric acid methyl ester. Since P3HT:PCBM blend is one most OPV community, existing research provides a solid foundation for us to compare benchmark our innovative characterization...
Abstract Most current highly efficient organic solar cells utilize small molecules like Y6 and its derivatives as electron acceptors in the photoactive layer. In this work, a molecule acceptor, SC8‐IT4F, is developed through outer side chain engineering on terminal thiophene of conjugated 6,12‐dihydro‐dithienoindeno[2,3‐d:2′,3′‐d′]‐s‐indaceno[1,2‐b:5,6‐b′]dithiophene (IDTT) central core. Compared to reference C8‐IT4F, which lacks chains, SC8‐IT4F displays notable differences geometry (as...
Heavy-atom-free diethoxycarbonyl-BODIPY undergo SOCT-ISC and enable photopolymerization of acrylamide monomers inside a cellulose acetate matrix that was applied for holographic recording diffractive structures with high efficiency.
A series of new heavy-atom-free photosensitizers using 2,6-diethoxycarbonyl-BODIPY was designed and synthesized. Photoinduced electron transfer between the BODIPY meso-aryl subunits followed by formation triplet excited states via spin-orbit charge intersystem crossing (SOCT-ISC) studied steady-state ultrafast pump-probe transient optical spectroscopy. Highly efficient photosensitization observed for dyads bearing pyrene anthracene substituents, which exhibited singlet oxygen generation with...
