The method includes preparing a crystalline silicon substrate; performing an isotropic etching process of the substrate; and removing a saw damage on a surface of the substrate by performing an anisotropic etching process of the isotropically etched substrate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Tandem solar cell manufacturing method","description":"Discussed is a tandem solar cell manufacturing method including etching a crystalline silicon substrate, whereby a solar cell can be obtained which does not have a pyramid-shaped defect on a surface o","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11515443","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.
