{"doi":"10.1093/nsr/nwab031","title":"Molecular design revitalizes the low-cost PTV-polymer for highly efficient organic solar cells","abstract":"Abstract Developing photovoltaic materials with simple chemical structures and easy synthesis still remains a major challenge in the industrialization process of organic solar cells (OSCs). Herein, an ester substituted poly(thiophene vinylene) derivative, PTVT-T, was designed and synthesized in very few steps by adopting commercially available raw materials. The ester groups on the thiophene units enable PTVT-T to have a planar and stable conformation. Moreover, PTVT-T presents a wide absorption band and strong aggregation effect in solution, which are the key characteristics needed to realize high performance in non-fullerene-acceptor (NFA)-based OSCs. We then prepared OSCs by blending PTVT-T with three representative fullerene- and NF-based acceptors, PC71BM, IT-4F and BTP-eC9. It was found that PTVT-T can work well with all the acceptors, showing great potential to match new emerging NFAs. Particularly, a remarkable power conversion efficiency of 16.20% is achieved in a PTVT-T:BTP-eC9-based device, which is the highest value among the counterparts based on PTV derivatives. This work demonstrates that PTVT-T shows great potential for the future commercialization of OSCs.","journal":"National Science Review","year":2021,"id":148715,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":120,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9443,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2021-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":632697,"name":"Pengqing Bi","orcid":"0000-0001-7503-2232","position":1,"is_corresponding":false},{"id":632698,"name":"Jianqi Zhang","orcid":"0000-0002-3549-1482","position":2,"is_corresponding":false},{"id":108344,"name":"Jiao Liu","orcid":"0009-0009-2874-0354","position":3,"is_corresponding":false},{"id":632699,"name":"Jingwen Wang","orcid":"0000-0002-1484-201X","position":4,"is_corresponding":false},{"id":632700,"name":"Ye Xu","orcid":"0000-0003-2449-1775","position":5,"is_corresponding":false},{"id":632701,"name":"Zhixiang Wei","orcid":"0000-0001-6188-3634","position":6,"is_corresponding":false},{"id":632702,"name":"Shaoqing Zhang","orcid":"0000-0002-0148-9560","position":7,"is_corresponding":false},{"id":632703,"name":"Jianhui Hou","orcid":"0000-0002-2105-6922","position":8,"is_corresponding":false},{"id":633628,"name":"Junzhen Ren","orcid":null,"position":0,"is_corresponding":true}],"reference_count":39,"raw_metadata":null,"created_at":"2026-07-18T23:42:46.224799Z","pmid":"35371513","pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
