英文摘要	Non-fullerene organic solar cells are of broad and current interest in the field of organic solar cells, and show promising application in high performance solar cells. When designing conjugated molecules as non-fullerene materials, several parameters, such as absorption, energy levels, charge transport, and crystallinity should be considered. Among them, absorption spectra are an important parameter that determine the efficiency of sun-light harvesting. In this work, we explore a new near-infrared electron acceptor naphthalenediimide-porphyrin (NDI-Por) by using electron-donating porphyrin as the core, and four NDI as end groups with ethynyl as linkers attached to the meso-position of porphyrin. This star-shaped molecule exhibits absorption spectra up to 900 nm. NDI-Por was incorporated into non-fullerene solar cells as an electron acceptor, and together with a wide-band gap polymer donor, an initial power conversion efficiency of 1.80% could be achieved. In particular, the solar cells exhibit a broad photo-response from 300 to 900 nm. Our results demonstrate that it is an efficient strategy to incorporate porphyrin into conjugated molecules to realize non-fullerene materials with near-infrared absorption spectra.
