On occasion, this has led to very high efficiency devices that have set world records. https://images.squarespace-cdn.com/content/v1/5a7a69cbf09ca4e43d8944cb/1528461231555-PZH2YNYBW4MHT1D9LDWU/SQHirstplot.png Research Areas - Thermodynamicsof Photovoltaic Power Conversion To attain the highest efficiency the QPV group seeks to understand the losses that are inherent to the photovoltaic power conversion process. This was first correctly established by Shockely and Queisser in 1961, plotting the blue 'power out' curve shown. In 2011 the QPV group accounted for other fundamental losses in the solar cell resulting in one of our highest cited papers on account of the clear exposition of the problem. We have since considered the opportunity that non-isotropic photon emission holds on the efficiency of photovoltaic devices, resulting in a minor revision to the Shockley-Queisser efficiency limit and demonstrated this in strained quantum well devices. https://images.squarespace-cdn.com/content/v1/5a7a69cbf09ca4e43d8944cb/1528465755996-0BI0BOEYVMNI0N46UQIR/imperialoct2010-446_076445_001.jpg Research Areas https://www.qpvgroup.org/about daily 1.0 2023-06-19 https://images.squarespace-cdn.com/content/v1/5a7a69cbf09ca4e43d8944cb/1517980305332-2N3V81TVIBT5IR67L053/solar_cell_2_064853_001.jpg About - Quantum Photovoltaics https://www.qpvgroup.org/vacancies daily 0.75 2022-12-15 https://www.qpvgroup.org/phoebe-pearce daily 0.75 2024-10-01 https://www.qpvgroup.org/publications daily 0.75 2022-05-26 https://images.squarespace-cdn.com/content/v1/5a7a69cbf09ca4e43d8944cb/1517985048018-EQIG5GF64HSL4K94KIUA/1800x750_campus_section2.jpg Publications https://www.qpvgroup.org/people daily 0.75 2023-09-19 https://www.qpvgroup.org/ned-ekinsdaukes daily 0.75 2022-12-15 https://images.squarespace-cdn.com/content/v1/5a7a69cbf09ca4e43d8944cb/1528455365175-VRJCPFZR9PXV10Y5DVMF/Ned2018.jpg Ned Ekins-Daukes https://www.qpvgroup.org/pagenotfound daily 0.75 2019-02-03 https://images.squarespace-cdn.com/content/v1/5a7a69cbf09ca4e43d8944cb/1549158856755-3BKT8JTZK237AO9CI9KV/Screen+Shot+2019-02-03+at+12.53.35+pm.png Page not found. https://www.qpvgroup.org/new-page daily 0.75 2019-02-03 https://images.squarespace-cdn.com/content/v1/5a7a69cbf09ca4e43d8944cb/1549182493836-YZ2DOY327QE63WZ111TD/noct_eqn.png New Page https://images.squarespace-cdn.com/content/v1/5a7a69cbf09ca4e43d8944cb/1549182974514-AE1J71S0I37N5O5541N7/noct_eqn.png New Page https://www.qpvgroup.org/michael-nielsen daily 0.75 2023-06-19 https://images.squarespace-cdn.com/content/v1/5a7a69cbf09ca4e43d8944cb/1550469025555-QOI9MNGDO0G33VY0555F/facebook_1550468988156-20190218-164955670-20190218-164955723.jpg Michael Nielsen https://www.qpvgroup.org/andreas-pusch daily 0.75 2020-05-06 https://www.qpvgroup.org/udo-romer daily 0.75 2021-07-19 https://images.squarespace-cdn.com/content/v1/5a7a69cbf09ca4e43d8944cb/1589345479541-MDJSD9SRF3XBAG7NX5ZM/Udo-Romer-RLA_9565c-1200w.jpg Udo Römer https://www.qpvgroup.org/alex-lehmann daily 0.75 2020-05-17 https://www.qpvgroup.org/sazzad daily 0.75 2020-06-29 https://images.squarespace-cdn.com/content/v1/5a7a69cbf09ca4e43d8944cb/1593411173674-6XTGI16EKHJK8U6CVDNG/10922800_994461863905786_3712434047769192811_n.jpg Sazzad https://www.qpvgroup.org/anastasia daily 0.75 2023-06-19 https://images.squarespace-cdn.com/content/v1/5a7a69cbf09ca4e43d8944cb/f437bf8d-d580-48e1-a970-c289ee746fc2/anastasia.jpg Anastasia - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://www.qpvgroup.org/new-page-1 daily 0.75 2023-09-19 https://www.qpvgroup.org/new-page-3 daily 0.75 2024-04-02 https://images.squarespace-cdn.com/content/v1/5a7a69cbf09ca4e43d8944cb/8134c053-7a0b-4b42-bfa2-5fad4ed47f61/DSC_0030+%283%29.jpg Spectral Response https://images.squarespace-cdn.com/content/v1/5a7a69cbf09ca4e43d8944cb/f13b1f41-caac-486d-a64d-797a65486f34/DSC_0270.jpg Spectral Response - Make it stand out Whatever it is, the way you tell your story online can make all the difference.
