Under 1000 W\/m², a 1.7 m² panel at 20 percent efficiency delivers about 340 W. A single silicon junction is limited near 33 percent, the Shockley–Queisser limit; stacked cells beat it. Pixel-art kiss-cut sticker in 2, 3, 4 and 6 inches; equation, symbols and sources in the physics panel below.\u003c\/p\u003e","brand":"Printify","offers":[{"title":"2\" × 2\" \/ White","offer_id":50658856599655,"sku":"22174528958624215834","price":4.99,"currency_code":"USD","in_stock":true},{"title":"3\" × 3\" \/ White","offer_id":50658856632423,"sku":"20858491597298109338","price":6.99,"currency_code":"USD","in_stock":true},{"title":"4\" × 4\" \/ White","offer_id":50658856665191,"sku":"80230202398129650311","price":8.99,"currency_code":"USD","in_stock":true},{"title":"6\" × 6\" \/ White","offer_id":50658856697959,"sku":"63891790416959578872","price":11.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/8746\/9159\/files\/01_clean_e1faf76c-4c5e-4eeb-ab36-db31a860c1c3.jpg?v=1792806198","url":"https:\/\/pixelatedphysics.com\/products\/sunnel-solar-cell-efficiency-pixel-sticker","provider":"Pixelated Physics","version":"1.0","type":"link"}
