A series of acceptor-donor-acceptor simple oligomer-like small molecules based on oligothiophenes, namely, DRCN4T-DRCN9T, were designed and synthesized. Their optical, electrical, thermal properties photovoltaic performances systematically investigated. Except for DRCN4T, excellent obtained DRCN5T-DRCN9T. The devices DRCN5T, DRCN7T, DRCN9T with axisymmetric chemical structures exhibit much higher short-circuit current densities than those DRCN6T DRCN8T centrosymmetric structures, which is...
Organic photovoltaic cells based on small molecules show high performance in bulk heterojunction solar cells. Using the simple solution spinning process, DERHD7T/PC61 BM-based cell exhibits a power conversion efficiency of up to 6.10%.
A series of sp(2) carbon materials with different specific surface area (SSA) and controlled pore size distribution (PSD) were synthesized at large scale through a facile low-cost method. The SSA PSD these by using sources preparation methods. With total effective (E-SSA) PSD, the impacts on their capacitance performance investigated thoroughly, which demonstrated that both E-SSA played most important roles in performance. Furthermore, theoretical modeling was performed, results are...
The diverse molecular stacking tuned by peripheral halogens in non-fullerene acceptors (NFAs) significantly affects the physicochemical properties, film morphologies and thus power conversion efficiencies (PCEs) of organic solar cells (OSCs).
Abstract Developing dopant‐free hole transport materials (HTMs) to replace Spiro‐OMeTAD is a challenging but urgent issue for commercialization of state‐of‐the‐art n‐i‐p structured perovskite solar cells (PSCs).

A new non-fullerene small molecule with an acceptor-donor-acceptor (A-D-A) structure, FDNCTF, incorporating fluorenedicyclopentathiophene as core and naphthyl-fused indanone end groups, was designed synthesized. Compared the previous FDICTF phenyl-fused extended π-conjugation at group has only little impact on its molecular orbital energy levels, thus, open-circuit voltage (Voc) of solar cell devices been kept high. However, light absorption mobility, together short-current density (Jsc)...
Both the efficiency and stability of low-cost organic solar cells are central components for meeting requirements commercialization photovoltaics (OPV). Furthermore, relationship between chemical structure an active material morphology its effects on is still largely undetermined. Additionally, both kinetic thermodynamic states layer can have a huge impact stability, even when structures materials applied in especially same or similar. Here, using two series acceptor–donor–acceptor...

First, a novel multilayer unit-cell based on polarization turning concept is proposed to achieve the single-bit phase shift required for reconfigurable applications. The principle of discussed using current model and space match condition, along with simulations corroborate design performance criteria. Then, an offset-fed configuration developed verify antenna application, its transformation property...
Success in obtaining higher-order twistarenes with precise structures is very important for fundamentally understanding the relationship between and physical properties/optoelectronic applications. In this research, by using advantages from a retro-Diels-Alder process (clean reaction) cross-conjugated nature of pyrene unit, novel dodeca-twistarene was prepared first time. Its structure, confirmed single-crystal XRD analysis, indicates that it possesses twisted angle (≈30°), two neighboring...
