“…This is due to the spectral response of amorphous silicon solar cells being in the in the ultraviolet to red (~300-750nm) region where the sunlight spectra (and simulator light spectra) changes the most with air mass. Similar behavior has also been extracted from outdoor measurements and reported in [9], [10] and [11]. This drop of relative short circuit current has also a direct effect on the device efficiency (Fig.…”

This paper demonstrates photovoltaic (PV) device performance measurements for energy rating and energy yield calculation derived indoors with an LED-based solar simulator prototype under varying irradiance (G), temperature (T) and spectrum (E), opening the possibility for much faster and more accurate energy yield prediction than previously possible from measurements acquired either indoors or outdoors, with the additional inclusion of spectral influences.The main aspects of the LED-based solar simulator used are described briefly and the measurement method with its requirements is explained in detail. Also presented are the first performance measurements made with an amorphous silicon solar cell; measuring the spectral effects reported in outdoor measurements for the first time in the laboratory.Results show a good agreement with previously reported spectral effects from outdoor measurements and underline the importance to consider all three environmental vectors (irradiance, spectrum and device temperature) for energy yield focused measurements.

“…In the case of c-Si technologies an increase in efficiency at high AM and clear sky conditions has been reported (King et al, 2004;Zdanowicz et al, 2003), while other investigations performed on c-Si modules mounted on a tracker under clear sky conditions showed a slight decrease in performance with increasing AM (Kenny et al, 2006). CdTe and a-Si technologies have a narrower spectral response which ranges approximately between 350 -800 nm and this leads to lower photon absorption.…”

“…Hence, the operating temperature results variation in at the same irradiation levels with an enhancement of up to 2% and a winter reduction up to 1% [20,43,44]. This effect is severe for thin film devices, yet the parametric sensitivity of these devices to variations in the incident spectrum is still not fully understood but several studies were evaluated to define the main reason of variation for different materials, especially for a-Si based solar cells [8,20,23,35,[42][43][44][45]60]. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 10 is spectrum dependent as given in Eq.…”

Numerous performance analysis studies have been carried out to assess the magnitudes of these effects on different technology based PV devices [65][66][67][68][69][70][71][72][73][74][75][76][77][78].…”

The outdoor performance of photovoltaic modules is influenced by spectrum. Even if the irradiance level and the operating temperature is the same, performance difference of photovoltaic modules between the seasons can be increase up to 15% depending on the photovoltaic module type. In this paper, seasonal spectral irradiance effects on the outdoor photovoltaic module performance and previous studies has been summarised thoroughly. The spectrum indicators which are used for spectra characteristics, Useful Fraction and Average Photon Energy are described in detail. This study also indicates spectrum effects on PV performance and outlines the present studies investigating this effect.Keywords: spectral effect, photovoltaic module, outdoor performance, useful fraction, average photon energy 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 spectrum, and a module temperature of 25⁰C. However, STC are not representatives of actual outdoor conditions in most regions of the world. Therefore, it is suspected that the score of a PV module by power rating method under STC is different from the actual performance in outdoor conditions [1][2][3][4][5].The performance of photovoltaic (PV) modules installed outdoor is greatly influenced by various ambient environmental factors such as incident irradiance, the module temperature and the spectral irradiance distribution.In this study, solar spectrum, the spectral effects on PV performance is discussed. There are a lot papers presented in different organizations outlines the effect on the installed PV systems. More than 200 studies are reviewed and some of them are published in journals or conference proceedings, the rest are unpublished or contains only local data. Solar Spectrum and Additional Spectral Irradiance DescriptorsEmission of radiation from the sun contributes to the solar spectrum as observed from Earth. Just above the Earth's atmosphere, the radiation intensity, or Solar Constant, is about 1.353 kW/m 2 [6,7] and the spectral distribution is referred to as an air mass zero (AM0) radiation spectrum. The Air Mass is a measure of how absorption in the atmosphere affects the spectral content and intensity of the solar radiation reaching the Earth's surface. The Air Mass number is given by (1) where is the angle of incidence ( when the sun is directly overhead). Moreover, the outdoor solar spectrum distribution changes during a day because of the aerosol and water vapour. Hence, it is rare to fit the standard solar spectrum (Fig.1 Therefore, a new parameter, angle of incidence is defined to explain the position of solar rays on the plane [10]. is a measure of deviation of something from "straight on". A surface directly facing the sun has an of zero, and a surface parallel to the sun (such as a sunrise striking a horizontal plane) has an of 90°. Sunlight with an inc...
