This research involves developing a technology roadmap by device modeling and simulations to achieve \u0026gt; 23% efficiency target followed by development and implementation of required design features such as optimized boron emitter on front and tunnel oxide passivated contact (TOPCon) on the rear side of an n-type silicon wafer, in combination with advanced fine-line screen-printing metallization with floating busbars to attain the efficiency target. Carrier-selective passivating contacts consist of material structures in-between of c-Si and metal electrode, which effectively reduce electron-hole recombination through defect states at the c-Si surface while working as contacts to extract either electrons or holes from the c-Si absorber. A next-generation industry-compatible double-side passivated contacts solar cell structure is also proposed. This cell structure is composed of full area p-TOPCon on the rear and selective area n-TOPCon on the front side of an n-type Si wafer. Detailed modeling using practically achievable material and device parameters shows that ~25.4% efficiency is achievable with this design using traditional screen-printing.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Development of Low-Cost High-Efficiency Tunnel Oxide Passivated Contact Silicon Solar Cells "}],"uid":"28475","created_gmt":"2021-10-22 17:04:18","changed_gmt":"2021-10-22 17:04:18","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2021-10-29T15:00:00-04:00","event_time_end":"2021-10-29T17:00:00-04:00","event_time_end_last":"2021-10-29T17:00:00-04:00","gmt_time_start":"2021-10-29 19:00:00","gmt_time_end":"2021-10-29 21:00:00","gmt_time_end_last":"2021-10-29 21:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"434381","name":"ECE Ph.D. Dissertation Defenses"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"},{"id":"1808","name":"graduate students"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
