The quest for higher efficiency in organic photovoltaic (OPV) devices is a continuous endeavor, and the selection of optimal materials plays a crucial role. NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of this innovation, offering OPV Donor D18 (PCE18), a polymer donor that has demonstrated remarkable performance, enabling power conversion efficiencies exceeding 18% in cutting-edge solar cell designs.

D18 (PCE18) is not just another organic semiconductor; it is a specifically designed narrow bandgap copolymer engineered to facilitate efficient energy conversion in OPVs. Its backbone structure alternates between electron-donating benzodithiophene (BDT) segments and electron-accepting dithienobenzothiadiazole (DTBT) moieties. This unique configuration results in a molecular plane with a greater degree of conjugation, which is fundamental to achieving high charge carrier mobility. Specifically, the high hole mobility of 1.59 × 10-3 cm2 V-1 s-1 attributed to D18 is a key factor contributing to its success in high-efficiency applications.

The impact of this material is clearly evidenced in recent scientific advancements. When paired with suitable electron acceptors, such as Y6, D18 (PCE18) has been employed in single-junction non-fullerene polymer solar cells (NF-PSCs) that have achieved an impressive device efficiency of 18.22%, with a certified efficiency of 17.6%. These figures represent the current world record for binary systems utilizing such donor materials and underscore the exceptional capabilities of D18 (PCE18).
