Abstract

Spiro-OMeTAD (2,2',7,7'-tetrakis (N, N-di-p-methoxyphenylamine) -9,9'-spirobifluorene) has been a key hole transport material (HTM) in perovskite solar cells (PSCs) due to its excellent charge transport properties and compatibility with high-efficiency devices. However, its widespread application in PSCs is hindered by the limitations such as environmental sensitivity, high production costs, and the optimal conductivity via chemical doping process. This review explores three critical approaches to addressing these challenges: 1) the Spiro-OMeTAD-based additives and specialized treatments, including oxygen-free processes, that enhance stability and performance; 2) the development of Spiro-OMeTAD derivatives designed to improve HTM properties such as moisture resistance; 3) the exploration of Spiro-OMeTAD substitutes with cost-effectiveness and better scalability. By examining these strategies, this review provides the insights based on the traditional Spiro-OMeTAD to improve the efficiency, stability, and commercial viability of PSCs. The findings are intended to guide future research and development in the advancing PSCs technology towards broader adoption.

期刊介绍： Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics. Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews. A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal. Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
