A method of manufacturing a thin-film solar cell is also provided, which includes forming a back contact layer on a glass substrate using sputtering; forming a light-absorbing layer on the back contact layer using spraying; forming a buffer layer on the light-absorbing layer using chemical vapor deposition; forming a window layer on the buffer layer using sputtering; and forming an upper electrode layer on the window layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of manufacturing thin-film light-absorbing layer, and method of manufacturing thin-film solar cell using the same","description":"Disclosed is a method of manufacturing a thin-film light-absorbing layer using spraying, including mixing precursor solutions comprising CuCl2, InCl3 and SeC(NH2)2 under a nitrogen atmosphere at room ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8501524","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
