Summary of "Design of New n-Type Porphyrin Acceptors with Subtle Side-Chain Engineering for Efficient Nonfullerene Solar Cells with Low Energy Loss and Optoelectronic Response Covering the Near-Infrared Region."

A series of tailor-made highly efficient and near-infrared porphyrin-based acceptors is designed and synthesized for fullerene-free bulk-heterojunction (BHJ) organic solar cells (OSCs). Constructing BHJ active layers using a PTB7-Th donor and porphyrin acceptors (P-x), which have complementary absorption, accomplish panchromatic photon-to-current conversion from 300 to 950 nm. Our study shows that side-chains of the porphyrin acceptors fairly influences the molecular ordering and nanomorphology of the BHJ active layers. Significantly, porphyrin acceptor with four dodecoxyl side-chains (P-2) achieves an open-circuit voltage (VOC) of 0.80 V, a short-circuit current density (JSC) of 13.94 mA cm-2, a fill factor (FF) of 64.8%, and overall power conversion efficiency (PCE) of 7.23%. This great performance is attributable to the ascendant light-harvesting capability in the visible and NIR region, a high-lying LUMO energy level, a relatively high and more balanced carrier mobilities, and more ordered face-on molecular packing, which is beneficial for obtaining high VOC and JSC.

Medical and Biotech [MESH] Definitions

Flavoproteins that serve as specific electron acceptors for a variety of DEHYDROGENASES. They participate in the transfer of electrons to a variety of redox acceptors that occur in the respiratory chain.

A group of antibiotics that contain 6-aminopenicillanic acid with a side chain attached to the 6-amino group. The penicillin nucleus is the chief structural requirement for biological activity. The side-chain structure determines many of the antibacterial and pharmacological characteristics. (Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed, p1065)

An enzyme that phosphorylates myosin light chains in the presence of ATP to yield myosin-light chain phosphate and ADP, and requires calcium and CALMODULIN. The 20-kDa light chain is phosphorylated more rapidly than any other acceptor, but light chains from other myosins and myosin itself can act as acceptors. The enzyme plays a central role in the regulation of smooth muscle contraction.

A group of enzymes that transfers two phosphate groups from a donor such as ATP to two different acceptors. (From Enzyme Nomenclature, 1992) EC 2.7.9.

An approach, process, or methodology which emphasizes credible evidence and the best available scientific knowledge, judiciously integrated to achieve the best possible outcomes in structural design. For example, the design of a new OUTPATIENT CLINIC might incorporate a review of published research on outpatient clinic design, decisions on similar past projects, along with interviews with staff and consumers.
