Anti-soiling coatings for solar cell cover glass: Climate and surface properties influence

Ab initio study of the Surface Passivation influence on electronic and optical Properties of (001) SbNSr3 anti-perovskite Surface

In this research, the electronic and optical properties of the (001) surface of SbNSr3 with SbSr and NSr2 terminations and surface passivation impact on electronic properties were investigated. The calculations were done within density functional theory and using pseudo-potential method. HSE hybrid functional was used for exchange correlation potential. The surface calculations were performed t...

Efficiency Enhancement of Si Solar Cells by Using Nanostructured Single and Double Layer Anti-Reflective Coatings

The effect of single and double-layer anti-reflective coatings on efficiency enhancement of silicon solar cells was investigated. The reflectance of different anti-reflection structures were calculated using the transfer matrix method and then to predict the performance of solar cells coated by these structures, the weighted average reflectance curves were used as an input of a PC1D simulation....

Influence Of SINx: H And SIOx Films On Optical And Electrical Properties Of Antireflective Coatings For Silicon Solar Cells

ABSRTACT: To increase the photon transmission in solar cells based on multicrystalline silicon, two different double layer antireflections (DARC1 and DARC2) were optimized and simulated, to optimize the antireflection double layer, we have developed a numerical simulation code with Matlab software package where we have used the method of transfer matrix to solve the optical equation. These solu...

The HelioClim Project: Surface Solar Irradiance Data for Climate Applications

Meteosat satellite images are processed to yield values of the incoming surface solar irradiance (SSI), one of the Essential Climate Variables. Two HelioClim databases, HC-1 and HC-3, were constructed covering Europe, Africa and the Atlantic Ocean, and contain daily and monthly means of SSI. The HC-1 database spans from 1985 to 2005; HC-3 began in 2004 and is updated daily. Their quality and li...
