Introducing light trapping structures into thin-film solar cells has the potential to enhance their solar energy harvesting as well as the performance of the cells; however, current strategies have been focused mainly on harvesting photons without considering the light re-escaping from cells in two-dimensional scales. The lateral out-coupled solar energy loss from the marginal areas of cells ha...

The photocatalytic degradation of the chemical dye AZO and dye effluents in different time duration has been investigated using biologically synthesized silver nanoparticles. Dye industry effluents and AZO dye undergo degradation to form harmless intermediate and colourless products following irradiation by UV and solar light in the presence of green synthesized silver nanoparticles. The degree...

Solar photocatalytic water splitting is considered as a potential method for hydrogen production as both solar energy and water are renewable. The major task is the design of suitable photocatalysts, which can work efficiently under solar radiation, especially under visible light. The performance of the visible light active photocatalysts synthesized till date is far from satisfactory for any p...

Light scattering is a method that has been employed in dye-sensitized solar cells for optical absorption enhancement. In conventional dye-sensitized solar cells, large TiO(2) particles with sizes comparable to the wavelength of visible light are used as scatterers by either being mixed into the nanocrystalline film to generate light scattering or forming a scattering layer on the top of the nan...

This paper presents the performance of solar cells under different electric lighting sources in indoor environments. Experiments are conducted for different solar technologies like polycrystalline Silicon, Amorphous Silicon and DyeSensitized .Measurements are done under illumination from incandescent, fluorescent and LED light sources in this paper. Also, simulations are done to find out the ma...

Human-made objects (e.g., buildings with glass surfaces) can reflect horizontally polarized light so strongly that they appear to aquatic insects to be bodies of water. Insects that lay eggs in water are especially attracted to such structures because these insects use horizontal polarization of light off bodies of water to find egg-laying sites. Thus, these sources of polarized light can becom...

There are currently no international norms which define a method for characterizing photovoltaic solar cells for indoor applications. The current standard test conditions are not relevant indoors. By performing efficiency simulations based on the quantum efficiency of typical solar cells and the light spectra of typical artificial light sources, we are able to propose the first step for develop...

Organic solar cells have become a suitable photovoltaic technology thanks to their flexibility, scalability and light weight layout. They offer many advantages over the prevalent silicon industry, however, their efficiency is around 11%, still below the usual 20% on commercially available silicon solar panels [1], [2]. In this work, we propose an innovative method to increase light absorption o...
