This requires a lift-off technique compatible with good quality III-N materials, with photovoltaic device fabrication and with subsequent bonding on a heterogeneous substrate.\u0026nbsp; This thesis work\u0026nbsp;demonstrates unprecedented\u0026nbsp;InGaN-based solar cells on 2-inch h-BN\/sapphire wafer and their transfer to glass with a backside reflector. III-N solar cells with various sizes and designs are processed and characterized on a full 2-inch wafer giving performances comparable to similar devices on sapphire. The subsequent crack-free transfer of the solar cells, enabled by Van der Waal bonded 2D layered h-BN, to a substrate with a backside reflector yields an increase in the short circuit current density of up to 20%. This demonstration of transferred InGaN-based solar cells on foreign substrates while increasing performance represents a major advance toward lightweight, low cost and high efficiency photovoltaic applications.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Design ad Fabrication of Nitride-based Solar Cells and Intergration for Tandem Cell "}],"uid":"28475","created_gmt":"2018-07-02 22:35:39","changed_gmt":"2018-07-10 19:17:21","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2018-07-16T16:00:00-04:00","event_time_end":"2018-07-16T18:00:00-04:00","event_time_end_last":"2018-07-16T18:00:00-04:00","gmt_time_start":"2018-07-16 20:00:00","gmt_time_end":"2018-07-16 22:00:00","gmt_time_end_last":"2018-07-16 22:00:00","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":""}}}
