Off-axis holographic lens spectrum-splitting photovoltaic system for direct and diffuse solar energy conversion.
This paper describes a high-efficiency, spectrum-splitting photovoltaic module that uses an off-axis volume holographic lens to focus and disperse incident solar illumination to a rectangular shaped high-bandgap indium gallium phosphide cell surrounded by strips of silicon cells. The holographic lens design allows efficient collection of both direct and diffuse illumination to maximize energy y...
متن کاملLens-Photovoltaic Cell Coupling in a Holographic Solar Concentration System
A solar concentration system formed by two holographic cylindrical lenses is proposed. It redirects part of the incident solar spectrum towards a PV cell, concentrating only the cell’s most efficient wavelength range, while the rest is transmitted, not causing overheating. Simulations with oneand two-axes tracking are carried out.
متن کاملPhotovoltaic and photoelectrochemical conversion of solar energy.
The Sun provides approximately 100,000 terawatts to the Earth which is about 10000 times more than the present rate of the world's present energy consumption. Photovoltaic cells are being increasingly used to tap into this huge resource and will play a key role in future sustainable energy systems. So far, solid-state junction devices, usually made of silicon, crystalline or amorphous, and prof...
متن کاملCompound Holographic Optical Element System for Splitting and Concentrating Solar Spectrum on Laterally- Arranged Multiple Band Gap Solar Cells
In present work a compound holographic system consisting of a diffraction grating and a holographic lens has been fabricated to disperse and focus different portion of solar spectrum on laterally arranged solar cells of different band gaps to achieve maximum efficiency operation. Such concentrators are light–weight, low-cost and do not require tedious processing for their mass production.
متن کاملSemiconductor-Based Photocatalytic, Photoelectrochemical, and Photovoltaic Solar-Energy Conversion
Semiconductor-based photocatalytic, photoelectrochemical, and photovoltaic solar-energy conversion has been considered very promising to address the energy and environmental challenges. At the heart of the technology is the lack of suitable semiconductor materials and efficient systems that can perform the solar-energy conversion efficiently and inexpensively. Much work needs to be done in this...
