Optimizing the performance of photovoltaic cells IBC (contact back interdigitated) by numerical simulation

Abstract

<p>Solar energy is the most widely shared and abundant source all over the world. This kind of energy is exploited to produce electricity directly by the solar photovoltaic cell. Indeed, silicon photovoltaic cells are the most widely spread technology. In the present article, we reported a numerical simulation of the interdigitated back contact (IBC) solar cell in order to obtain a higher conversion efficiency. The structure was realized on a p-type multi-crystalline silicon substrate, a p+ type amorphous silicon FSF, an n- type amorphous silicon based emitter, and a p- type BSF. The position of the emitter and the BSF were interdigitated and covered with ohmic contacts. The numerical simulation was carried out by SILVACO software under the Atlas module. The surface of structure was of a value of 10 cm<sup>2</sup> under illumination AM1.5g. We studied the effect of the geometrical and the physical parameters of the structure with IBC on the performance of the cell. The optimum obtained conversion efficiency was 20.83%; this result confirms the potential of the heterojunction silicon technology.</p>

“…It is a lightly doped n-type material with a carrier concentration of 10 15 /cm 3 . The n+ and p+ areas near the bottom of the cell had doping concentrations of 5x10 18 -5x10 21 . The p+ and n+ regions have widths of 80um and 20um, respectively.…”

Recent advances in passive cooling methods for photovoltaic performance enhancement

“…Photovoltaic (PV) modules convert sunlight into electricity with the aid of semiconductor material through the photovoltaic effect. However, the output performance of the PV module significantly depends on several external factors such as solar irradiance and ambient temperature, causing the reduction of electrical output and its life span [1]. The main problem which limits the electrical performances of PV technology is the overheating of the PV module.…”

Analysis and simulations of optimal geometry shapes of the 4 and 9 nano hole arrays (NHAs) with surface plasmonics and optical properties of biosensors systems

“…Plasmonic nanostructures have been extensively investigated both for scientific interest in their unique optical properties and for practical applications, such as optoelectronic devices, sensors, biomedical treatment; and so on [18,19]. Since plasmonic sensing requires simply an optical transmission spectrum, or only the transmitted intensity at one or a few wavelengths [20,21]. In this study we presented the differences between two holes arrays of 4 and 9 holes for different thickness (20,50,100) nm to characterize the optical properties for surface plasmons metals and to determine from these parameters the affects geometry and shape on sensors applications, biomedical and optoelectronic devices.…”
