Studying the Effect of Light Incidence Angle on Photoelectric Parameters of Solar Cells by Simulation

Abstract

It is crucial to examine the dependence of photoelectric parameters of solar cells on the light incidence angle. In the present study, two solar cell models have been developed using the Sentaurus Technology Computer-Aided Design software package. The light spectrum AM1.5 has been directed on the frontal surface of solar cells at different angles. It has been found that the angular coefficient of the photoelectric parameters of a solar cell with nanoparticles included, is two times more than that of a simple solar cell. Besides, it has been found that the efficiency of platinum nanoparticles induced solar cells is 2.15 times greater than simple solar cell efficiency. When the light incidence angle has been varied from 0 to 60 degrees, the short-circuit current has changed by 11% for simple solar cells and by 10% for solar cells with nanoparticles. Further, it has been observed that the variation of power for simple solar cells is 12.5%, while it is 10.5% for solar cells with nanoparticles. In addition, the short-circuit current of solar cells with nanoparticles has been found to be linear within a light incidence angle ranging from 0 to 60 degrees.

Lithography-Free, Large-Area Spatially Segmented Disordered Structure for Light Harvesting in Photovoltaic Modules

“…As θ is increased, J SC and η are gradually decreased (Figure e). Because the absorption intensity is decreased with the increase of incident angle, the J SC was reduced due to the lowered absorption intensity in the semiconductor layer, resulting in low exciton generation rate . Consequently, it reduces the total η following eq .…”

The Way of the Increasing Two Times the Efficiency of Silicon Solar Cell

“…We thought the inputting of nanoparticles into n region of silicon solar cell give chance to use resonance phenomenon in addition to changing the light spectrum. In our previous scientific works, it was found that its efficiency is good when size of the nanoparticle is 15-20 nm [8], [9]. In figure 2, dependence of absorption coefficient of Au, Ag, Cu, Pt NISSCs and SSC on wavelength are shown.…”

“…Motion of carriers forms current. Basically, connection between carrier concentration and current density is expressed by "general continuity equations" which are shown in formula (7) and (8).…”

Photovoltaic Solar Cells: A Review

“…where 'K i ' is the temperature coefficient of 'Isc'; T: operating temperature (K); 'G': solar insolation representing a full-sunlight condition as the illumination of sunlight varies widely in intensity and spectrum [96]. Second, modelling the reverse saturation current 'I rs ' as follows:…”
