Studying the effect of light intensity and the dust on efficiency of Silicon Solar cell

Abstract

In this paper, Two main effected parameters on the efficiency of solar cell has studied: the increasing in the amount of intensity of incident solar irradiance on the surface of silicon solar cell and accumulation of dust on the front face of solar cell. The parameters of silicon solar cell (Isc, Voc, pmax, η) have been studied under various quantities of solar irradiations (G= 100, 172,252 and 606W/m2 ) at a constant temperature (TC=25±2) ͦ C. The results showed an increasing in the value of conversion efficiency( fromη=7.1% to η=10%) with the increasing of intensity of solar flux. But the dust had a reverse effect on the value of conversion efficiency , thus after one week there was noticeable of(∆Isc= 5%) degradation at value of short circuit that lead to decrease of conversion efficiency.

Study the Effect of Doping and Thickness on I-V characteristic of Silicon Solar Cells Using PC1D Simulation

“…The researchers have a plan to obtain high efficiency with minimum cost. The External Quantum Efficiency can be noticed in the Figure (5). The curve is gradually lowered by increasing thickness from the emitter level of n-type, and a similar pattern can be seen in [15].…”

“…The external quantum efficiency, fill factor, and efficiency have been investigated. That discovered that the highest external Quantum efficiency was achieved at the low thickness n-type layer, shown Figure (5) and Table (4). According to Figure (5), increasing thickness does not continuously generate more efficiency.…”

“…That discovered that the highest external Quantum efficiency was achieved at the low thickness n-type layer, shown Figure (5) and Table (4). According to Figure (5), increasing thickness does not continuously generate more efficiency. The more efficient a PV module is, and thus the more cost-effective it becomes, the more attractive photovoltaic will be as an electricity source for both domestic and industrial use.…”

“…The solar cell designed with some basic parameters; the device area is (10 cm 2 ), and this study concentrated on a handful of factors such as thickness and doping concentration to see how they affect the I-V characteristics of silicon solar energy, other basic factors are fixed inside this inquiry, as demonstrated in the section below. This work included a thorough description of a front layer solar cell based on PC1D simulations [3][4][5]. The typical obstacles to providing electric energy are as follows: first, a very big geographical area is required in order to deploy high-efficiency solar cells; second, energy loss due to heat; and third, other energy sources, except for solar cells, are harmful to the environment.…”
