The efficiency of standard c-Si solar cells featuring diffused emitters and aluminum back surface fields (BSF) is limited by interface recombination. Alternatively the growth of intrinsic\/doped amorphous silicon (a- Si:H) layer stacks on c-Si effectively passivates the c-Si surface and simultaneously forms the emitter and BSF. Such Si heterojunction (HJ) solar cells can use thin c-Si wafers, benefit from low production cost of a-Si:H layers and enable the highest efficiencies. The focus of this work is the study of interfaces in a-Si:H\/c-Si heterostructures, particularly the electronic quality of the a-Si:H\/c-Si heterointerface and its effect on the subsequent a- Si:H\/c-Si HJ solar cell fabrication. Interface recombination modeling by considering the amphoteric nature of Si dangling bonds is in excellent agreement with measurements, and provides insight into the microscopic passivation mechanisms.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838109718\"\u003e\u003ch3\u003eModeling, experiments and solar cells\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838109718","offer_id":56006074663237,"sku":"9783838109718","price":89.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/cd07afab-5c3d-4d5f-a7ae-c0e74e83caa1.jpg?v=1777961353","url":"https:\/\/shop.autorenwelt.de\/products\/interface-properties-of-amorphous-crystalline-silicon-heterojunctions-von-sara-olibet","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
