“…Variation of UF value above standard AM1.5 spectrum value is called blue shift, whereas UF variation below AM1.5 spectrum is called red shift. In the field conditions, this variation in UF is mainly due to air mass and clouds, which also affects the irradiance, as discussed by Gottschalg et al [29]. Figure 8 shows the monthly variation of measured UF value for a-Si, HIT and mc-Si PV technologies.…”

The accuracy of outdoor performance of a photovoltaic (PV) array can be improved by considering the spectral effects. In this paper, the impact of seasonal spectral variations on the three different silicon PV technologies: single junction amorphous silicon (a-Si), Heterojunction with Intrinsic Thin-layer (HIT) and multi crystalline silicon (mc-Si) has been presented first time in Indian environmental conditions. The spectral effect on HIT PV module technology has been presented first time along with the first simultaneous study of variation in spectral indicators by useful fraction (UF), average photon energy (APE) and spectral mismatch factor (MMF), based on monthly and seasonal data. The maximum observed variation in UF was 26.4, 8.2, 10.8 %, while in MMF, variation was up to 24.7, 7.6, 8.2 % for a-Si, HIT and mcSi, respectively, and in APE variation was up to 15.3 %. Among all three technology modules, first time reported HIT technology showed the least variation while maximum variation was observed in a-Si technology. The observed spectral effect variations have been discussed on Performance Ratio and compared with reported results of other global sites. The value and trends of spectral parameters are important to understand the effect of spectral variation on different technology. This study is especially important in Indian subcontinent perspective because of the strong monsoon season, where observed variation in the spectrum-related parameter found to be highest among all the seasons.

“…Several authors have presented spectral effects by calculating the fraction of the solar irradiation that is usable by each PV technology (Gottschalg et al, 2003). Others have included the average photon energy (APE) parameter, even though this requires knowledge of the spectrum under varying conditions (Gottschalg et al, 2005;Norton et al, 2011). Empirical models have also been considered to account for the influence of the solar spectrum on the short circuit current (Huld et al, 2009).…”

“…Therefore, the dependence of PCE on these factors, and in particular its diurnal dependence provides information for the practical application of OPVs for the solar generation of electricity. Diurnal behavior has been studied for inorganic photovoltaics [6,7], while such information for polymer OPVs is limited [8,9], and completely absent for small molecule OPVs.…”

a b s t r a c tWe measure the diurnal dependence of the operating characteristics of tetraphenyldibenzoperiflanthene (DBP):C 70 planar-mixed heterojunction small-molecule organic photovoltaic (OPV) cells with 2,2 0 ,2 00 -(1,3,5-benzenitryl tris-[1-phenyl-1H-benzimidazole] (TPBi):C 70 electron-filtering cathode buffer layers. Over the course of a day, efficiency gradually increases as a result of a concomitant increase in shortcircuit current, while the fill factor and open-circuit voltage remain constant. The results are analyzed on the basis of independent measurements of temperature-and intensity-dependent OPV performance. The power conversion efficiency is maximized slightly below 1 sun intensity and at 40 C, which is beneficial for practical outdoor operation. We attribute the increased short circuit current with temperature to broadening of the absorption spectrum due to population of phonon states along with increased charge mobility, which also results in an increase in fill factor.
