We use Silvaco software (atlas tcad) simulation to investigate the effect of dielectric layer deposed on rear surface of solar cells passivated emitter and rear totally diffused (PERT). For an improved performance for this solar cell, several physical factors must be considered, such as the light trapping behavior, and the resulting passivation performance and rear surface recombination currents were investigated. Particular consideration will be given to the back surface reflector (BSR) impact on reflection surface, interface passivation, and on the I–V characteristics. Numerical simulations show that using a layer of two dielectrics (SiNx/SiO2) with optical indices and thickness optimized in combination with contacts located (optimized metallization fraction f) at the rear surface allow for energy conversion efficiencies of 21.26% compared to a single layer of dielectric SiN 21.01%.

“…Among the different constrains to fabricate high efficiency PEDO:PSS/n-Si heterojunction solar cells, the reflection of the incident light by the surface of solar cell is a key source of losses for photovoltaic conversion as Si surface reflects more than 30% as well as PEDOT:PSS on Si substrate reflects ∼20% of the incoming light [10,16]. These optical losses can be minimized by designing anti-reflection structure for crystalline silicon solar cells as it ensures a high photocurrent by reducing the reflectance.…”

In this paper, we present a theoretical model for the optimization of multilayer anti-reflection coatings for PEDOT:PSS/c-Si heterojunction solar cell based on optical interference transfer-matrix theory. A comprehensive idea of designing multilayer anti-reflection coatings (ARCs) on the solar cell and minimization of the overall reflectance is provided in this work. Optical reflectance values for various single, double and three layer anti-reflection coatings on PEDOT:PSS deposited c-Si substrate have been deduced using a MATLAB program and compared with that of the measured value. The reflectance value is calculated to be lower than 4% in the visible wavelength spectra for ARC by alternately using high and low refractive index materials. This low value of reflectance suggests that the anti-reflection coating layers proposed in this study can be employed as the standard ARC materials for optical coatings of the PEDOT:PSS/c-Si heterojunction solar cells.

Abstract.This article aims to numerically analyze the cooling system of photovoltaic device using mixture multiphase model. Aluminum oxide (Al2O3)-water nanofluids at various concentration of 0, 0.5, 1 and 2 vol.% were used as cooling fluid for photovoltaic module. The constant and uniform heat flux of 800 W/m 2 was applied on photovoltaic (PV) module and the various cooling fluids flowed under PV module at Reynold number of 200 and 500. The temperature distribution and local heat transfer coefficient of cooling fluid were observed. The results show that increasing concentration of Al2O3 nanoparticle enhances the local heat transfer coefficient and decreases the temperature of PV cell. The significant enhancement of convection heat transfer of Al2O3-water nanofluid occur at entrance region. The operating temperature of PV cell can be decreased till 303 K for 2 vol.% Al2O3-water nanofluid at Reynold number of 500. IntroductionSolar energy is one of the most abundant renewable energy resources. The electrical devices which convert solar energy into electrical energy via photovoltaic mechanism such as silicon have been developed to gain maximum performance. One of the main factor that can decrease the efficiency of photovoltaic cells is temperature [1]. Moreover, the effect of temperature in photovoltaic devices also decrease the life time and stability of PV system. The cooling mechanism is one of the solution which is applied by researcher to decrease the operating temperature of PV panels. The various types of fluids which can be used as PV cooling system are air, water, ethylene glycol and nanofluid.Nanofluid is a fluid which dispersed nanomaterials with size typically of 1 to 100 nm. The use of nanomaterials have attracted the interest for many applications such as semiconductor, solar cells, nanofluid, sensor, and etc [2][3][4][5]. The dispersion process of nanoparticle will enhance thermal conductivity and specific heat of fluid [6]. The addition of Al2O3 nanoparticles into water have been reported to increase the performance of convection heat transfer [6]. The heat transfer characteristic of nanofluid had been successfully investigated by single-phase and multi-phase model [7,8]. However, the multi-phase model produce heat transfer prediction which is more accurate than the single-phase model, because the disorder movement of nanoparticle and its interaction with base fluid also considered. Movareji, et al [8] showed that Al2O3-water nanofluid under heat flux constant in the discrete phase model had enhancement in heat transfer coefficient and a good agreement with experimental results. Thus, this work will investigate the numerical investigation of Al2O3-water nanofluid as cooling fluid for photovoltaic cells by using two-phase mixture model approach. The
