We couple 3D ray tracing with TMM thin-film boundary conditions for optical simulations and solve Poisson’s drift-diffusion equations to calculate carrier recombination under both front and rear illumination. For front (rear) AM1.5G illumination at normal incidence, regular inverted pyramids out-perform planar surfaces and upright pyramid texture efficiencies by 17.1% rel. (17.9% rel.) and 1.4% rel. (1.0% rel.), respectively. Reduced carrier loss for inverted pyramid textures is calculated to be primarily due to a reflectivity decrease of 63% (76%) compared to planar surfaces which results in enhanced carrier-generation at depths further into the c-Si substrate. The benefit of inverted pyramidal light-trapping will be further enhanced when higher angles of incidence are considered, with angular performance particularly relevant for the rear-side.","PeriodicalId":6780,"journal":{"name":"2021 International Conference on Numerical Simulation of Optoelectronic Devices (NUSOD)","volume":"28 2 1","pages":"55-56"},"PeriodicalIF":0.0,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89905443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
