The performance of Si sub-cell is investigated under LSC spectrum and is compared against the measurement done under 1 \u03bcm thick InGaP filter which mimics the spectrum seen by Si bottom cell in a conventional III-V/Si tandem.

", "abstract": "We propose a design for a concentrated photovoltaic (CPV) module with features that can capture both direct and diffuse sunlight. This approach uses a luminescent solar concentrator (LSC) sheet that includes quantum dots, and a tailored optical coating that enhances concentration and delivery of sunlight to the micro-PV cells. In addition, the light not captured by the quantum dots impinges on a tandem solar cell beneath the LSC sheet. The design of the LSC focuses on lowering the number of expensive micro-PV cells needed within the concentrator waveguide, thus reducing system costs while maintaining high efficiency. The design also allows the module to be effective without a tracking system, making it attractive to all PV markets.", "date": "2017-06", "date_type": "published", "publisher": "IEEE", "place_of_pub": "Piscataway, NJ", "pagerange": "1737-1740", "id_number": "CaltechAUTHORS:20181113-075306386", "isbn": "978-1-5090-5605-7", "book_title": "2017 IEEE 44th Photovoltaic Specialist Conference (PVSC)", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20181113-075306386", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "ARPA-E", "grant_number": "DE-AR0000627" } ] }, "doi": "10.1109/PVSC.2017.8366508", "primary_object": { "basename": "1710.00034.pdf", "url": "https://authors.library.caltech.edu/records/s5tpp-h2g31/files/1710.00034.pdf" }, "resource_type": "book_section", "pub_year": "2017", "author_list": "Needell, David R.; Nett, Zach; et el." } ]
