Issue Date: | 2015 | Volume: | 11th International Conference on Concentrator Photovoltaic Systems: CPV-11 | Editors: | Siefer, Gerald; Baudrit, Mathieu; Antón, Ignacio | Series: | AIP CONFERENCE PROCEEDINGS | Number: | 1679 | Issue: | 1 | First Page: | 050004 | Abstract: | In this work we have developed a combined heat and power (CHP) prototype that operates at 2000 × concentration based on reflective optics. The receiver consists of a InGaP/InGaAs/Ge triple-junction solar cell in thermal contact with an aluminium heat sink driving a forced water flow. This CHP system was tested both indoor (DNI of 650 W/m2) and outdoor (DNI of 900 W/m2) under different conditions of fluid parameters as the flow rate (ranging from 0.2 liters/min to 1.2 liters/min) and temperature (ranging from 25 °C to 60 °C). Electrical and thermal power were determined by acquiring IV curves and by measuring the heat subtracted from the cell while it delivered the maximum electrical power, respectively. The obtained results demonstrate that this CHP system achieves a total efficiency of about 80%, shared between the electrical (30%) and the thermal one (50%). | Conference Name: | 11th International Conference on Concentrator Photovoltaic Systems: CPV-11 | Conference Place: | Aix-les-Bains, France | Conference Date: | 3-15 April, 2015 | URI: | http://hdl.handle.net/20.500.12386/24207 | URL: | https://aip.scitation.org/doi/abs/10.1063/1.4931525 | ISSN: | 0094-243X | ISBN: | 978-0-7354-1326-9 | DOI: | 10.1063/1.4931525 | Bibcode ADS: | 2015AIPC.1679e0004B | Fulltext: | open |
