Abstract
Developing cost-effective p-type semiconducting polymers with desirable electrical properties and thermal tolerance is essential for the practical application of n-i-p type perovskite solar cells. In this study, we synthesized a semiconducting copolymer, p-POZOD-ENEM, via direct arylation polycondensation. This copolymer features an alternating main chain of phenoxazine, ethylenedioxythiophene, dimethoxynaphthalene, and ethylenedioxythiophene. The theoretical HOMO energy level of p-POZOD-ENEM is 70 meV deeper than that of the homopolymer poly(10-(2-octyldodecyl)phenoxazine-3,7-diyl) (p-POZOD), yet both are comparable to the established material spiro-OMeTAD. Furthermore, p-POZOD-ENEM exhibits higher glass transition temperature, hole mobility, and conductivity than both p-POZOD and spiro-OMeTAD, along with enhanced film morphology. Perovskite solar cells utilizing p-POZOD-ENEM as the hole transport material achieved an average power conversion efficiency of 25.0% and maintained good stability under thermal storage at 85 °C and operation at 45 °C.

期刊介绍:
ACS Energy Letters is a monthly journal that publishes papers reporting new scientific advances in energy research. The journal focuses on topics that are of interest to scientists working in the fundamental and applied sciences. Rapid publication is a central criterion for acceptance, and the journal is known for its quick publication times, with an average of 4-6 weeks from submission to web publication in As Soon As Publishable format.
ACS Energy Letters is ranked as the number one journal in the Web of Science Electrochemistry category. It also ranks within the top 10 journals for Physical Chemistry, Energy & Fuels, and Nanoscience & Nanotechnology.
The journal offers several types of articles, including Letters, Energy Express, Perspectives, Reviews, Editorials, Viewpoints and Energy Focus. Additionally, authors have the option to submit videos that summarize or support the information presented in a Perspective or Review article, which can be highlighted on the journal's website. ACS Energy Letters is abstracted and indexed in Chemical Abstracts Service/SciFinder, EBSCO-summon, PubMed, Web of Science, Scopus and Portico.
