Abstract

Domesticating solar energy by exploiting photovoltaic technology has become a quintessential strategy for future global energy production. Since 2015, non-fullerene organic solar cells (NF-OSC) have attracted a great deal of attention owing to the marvellous properties of non-fullerene acceptors (NFA) such as structural versability, broad absorption, suitable energy levels, tunable charge transport and morphology, leading to remarkable accomplishments in power conversion efficiency (PCE) from 1% to nearly 20%. One class of materials is provided by the fused ring aromatic indacenodithiophene (IDT) and its derivatives, which are emerging continuously as promising next-generation building blocks to construct high performance photovoltaic materials. Encouraging PCEs of more than 15% have been achieved in their binary NF-OSCs, while careful device engineering and proper amalgamation of a third component have led to PCEs of almost 18% in ternary devices. This review surveys recent developments in the area of IDT-based materials for photovoltaic applications. Different strategies to develop efficient IDT-based NFA and factors influencing the bandgaps, molecular energy levels, charge transport properties, and film morphologies, as well as the photovoltaic performance of these materials, are discussed.

非富勒烯有机太阳能电池用吲哚二噻吩基受体材料的研究进展

利用光伏技术实现太阳能的国产化已经成为未来全球能源生产的一个典型战略。自2015年以来，非富勒烯有机太阳能电池(non-fullerene organic solar cells, NF-OSC)由于其具有结构通用性、广泛吸收、合适的能级、可调谐的电荷输运和形态等特性而备受关注，其功率转换效率(PCE)从1%提高到近20%。一类材料是由熔融环芳香吲哚二噻吩(IDT)及其衍生物提供的，它们作为构建高性能光伏材料的下一代基石不断涌现。在他们的二进制NF-OSCs中，pce已经达到了令人鼓舞的15%以上，而仔细的设备工程和第三个组件的适当合并使得三元器件的pce接近18%。本文综述了近年来光伏应用中硅基材料的研究进展。本文讨论了开发高效基于idf的NFA的不同策略，以及影响这些材料的带隙、分子能级、电荷输运性质和薄膜形态以及光伏性能的因素。图形抽象

期刊介绍： Topics in Current Chemistry is a journal that presents critical reviews of present and future trends in modern chemical research. It covers all areas of chemical science, including interactions with related disciplines like biology, medicine, physics, and materials science. The articles in this journal are organized into thematic collections, offering a comprehensive perspective on emerging research to non-specialist readers in academia or industry. Each review article focuses on one aspect of the topic and provides a critical survey, placing it in the context of the collection. Selected examples highlight significant developments from the past 5 to 10 years. Instead of providing an exhaustive summary or extensive data, the articles concentrate on methodological thinking. This approach allows non-specialist readers to understand the information fully and presents the potential prospects for future developments.
