In the first step at least one B element is deposited, followed in the second by deposition of A and B elements at a deposition rate ratio Ar/Br, in the third at a ratio Ar/Br lower than the previous, in the fourth at a ratio Ar/Br higher than the previous, and in the fifth depositing only B elements to achieve a final ratio A/B of total deposited elements."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Thin-film photovoltaic device and fabrication method","description":"A method to fabricate thin-film photovoltaic devices including a photovoltaic Cu(In,Ga)Se2 or equivalent ABC absorber layer, such as an ABC2 layer, deposited onto a back-contact layer characterized in","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9786807","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.
