By using precise steel-stencil printing for narrow front metal fingers and a localized rear polysilicon contact, the design lowers contact resistance and parasitic optical losses. These improvements allow high-efficiency, cost-effective, and scalable solar cell production, addressing key challenges in the global photovoltaic market.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"z-0 flex min-h-[46px] justify-start\"><\/div>\n<div class=\"mt-3 w-full empty:hidden\">\n<div class=\"text-center\"><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/article>\n<\/div>\n<div class=\"pointer-events-none h-px w-px absolute bottom-0\" aria-hidden=\"true\" data-edge=\"true\"><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Researchers at the Chinese Academy of Sciences develope [&hellip;]<\/p>\n","protected":false},"author":9,"featured_media":8442,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[],"tags":[],"class_list":["post-8439","post","type-post","status-publish","format-standard","hentry"],"_links":{"self":[{"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/posts\/8439","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/users\/9"}],"replies":[{"embeddable":true,"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/comments?post=8439"}],"version-history":[{"count":1,"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/posts\/8439\/revisions"}],"predecessor-version":[{"id":8447,"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/posts\/8439\/revisions\/8447"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/media\/8442"}],"wp:attachment":[{"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/media?parent=8439"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/categories?post=8439"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/tags?post=8439"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
