The paper investigates the changes in the electrical and photoelectric characteristics and the effect of radiation on their properties. Solar cells based on а-Si:H and а-Si_0,88Ge_0,12:H films were fabricated in two-layer, three-layer, and two-plus-three-layer cascade structures; their performance characteristics were measured. It was found that for a cell area of 1,5 cm², the maximum power conversion efficiency (η) reaches 18,9 %.</div></div>","PeriodicalId":337,"journal":{"name":"International Journal of Hydrogen Energy","volume":"277 ","pages":"Article 157511"},"PeriodicalIF":9.2,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149157666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
