“…Table 2 summarizes the results of each CPV configuration, obtained during the selected days. As mentioned in the introduction, the following CPV configurations are considered in this study: Further information about the external quantum efficiency (EQE) of the MJ solar cells and transmittance of the Fresnel lenses can be found in [14].…”

Featured Application: This study presents a straightforward method based on analytical equations for applying a spectral correction on multijunction concentrating photovoltaics taking into account the optics.Abstract: Photovoltaic (PV) devices are spectrally selective, and their performance is influenced by unavoidable spectral variations. In addition, multijunction-based concentrating photovoltaic (CPV) devices show a strong spectral dependence due to the series connection of various junctions with different absorption bands, and also due to the use of concentrator optics. In this work, the accuracy of a new set of analytical equations that quantify the spectral impact caused by the changes in air mass (AM), aerosol optical depth (AOD) and precipitable water (PW) is discussed. Four different CPV devices based on lattice-matched and metamorphic triple-junction solar cells and a poly(methyl methacrylate) (PMMA) and silicon-on-glass (SoG) Fresnel lenses are considered. A long-term outdoor experimental campaign was carried out at the Centre for Advanced Studies on Energy and Environment (CEAEMA) of the University of Jaén, Spain. Results show a high accuracy in the estimations of the spectral factor (SF), with an average mean absolute percentage error (MAPE) within 0.91% and a mean relative error (MRE) within −0.32%.

“…The equations, boundary conditions and input data for the EM and FETM models are presented by Theristis and O'Donovan [13,16]. The spectral performance is evaluated using the spectral factor (SF) [17] and the spectral matching ratio between the top and middle subcells (SMR) [18] as criteria. SF is the normalisation of the short-circuit current density (J sc ).…”

The performance of High Concentration Photovoltaic (HCPV) receivers is influenced by changes in the solar spectrum and operating solar cell temperature (Tcell). Since the solar spectrum is affected by the variation of air mass (AM), aerosol optical depth (AOD) and precipitable water (PW), it is important to investigate their impact on the performance of HCPV receivers. It is also known that the direct normal irradiance (DNI) and ambient temperature (Tamb) are dominant factors that can influence the operating Tcell. In this study, Class I data from the NREL’s typical meteorological year (TMY3) database are used in order to predict the energy yield (Eyield) of a HCPV receiver in two USA sites with relatively high annual direct normal irradiation; Las Vegas, NV and Tucson, AZ. The results show that, although the annual average Tcell in Tucson is higher by 1.8°C and the number of “sunny hours” are 20 less than Las Vegas, the Eyield is still higher by 1.6%. The annual spectral losses in Las Vegas and Tucson were found to be 5% and 3% respectively

“…Module IV curves are obtained on a minute by minute basis along with spectral data from the SSIM. Measured currents are scaled to CSTC values using the measured spectrum and concentrator spectral response [6]. Voltages are shifted according to the product of the V OC temperature coefficient and cell temperature, which is measured via the "Voc, Isc Method" [7,8].…”
