On the impact of solar spectral irradiance on the yield of different PV technologies

Effect of seasonal spectral variations on performance of three different photovoltaic technologies in India

“…This large variation may be due to the oceanic effect on air mass variation which is not present at the Indian site. For another site located in Germany, the APE value variation was reported to be from 1.8 to 2 eV (11.1 %) for the wavelength range of 350-1050 nm [10]. In this case, the measurement spectral range was limited up to 1050 nm, which could be one of the main reasons of this small variation.…”

“…MMF is a correction factor applied to the short circuit current by taking into consideration the spectral mismatch between standard AM1.5 spectrum to the actual spectrum measured under outdoor condition at the time of measurement [10]. [26], a and b are wavelength (k) ranges of spectroradiometer from 350 nm and 1700 nm.…”

“…[26], a and b are wavelength (k) ranges of spectroradiometer from 350 nm and 1700 nm. MMF is the factor which expresses the quantity more or less irradiance observed by the device under test at current conditions compared to the reference device [10].…”

“…A detailed literature survey shows that several researchers reported spectral effects on PV module performances at different places, using different spectrum parameters, for different module technologies, using spectrum-based models and softwares and in different context, while interrelating with other parameters like temperature, module efficiency, etc. [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21].…”

“…Further, corrections have been proposed for the incident spectrum at UK site, to include seasonal changes for single and multi-junction a-Si modules [9]. At another site in Germany, annual spectral impact and its uncertainty on a-Si, CdTe, crystalline silicon (c-Si) and CIGS technologies have been estimated and related with APE and MMF [10,11]. The highest annual spectral impact and uncertainty were reported in a-Si.…”
