Optical component analysis for ultrahigh concentrated photovoltaic system (UHCPV)

Fresnel-based Concentrated Photovoltaic (CPV) System with Uniform Irradiance

Different designs have been presented to achieve high concentration and uniformity for the concentrated photovoltaic (CPV) system. Most of the designs have issues of low efficiency in terms of irradiance uniformity. To this end, we present a design methodology to increase irradiance uniformity over solar cell. The system consists of an eight-fold Fresnel lens as a primary optical element (POE) ...

Design of the Secondary Optical Elements for Concentrated Photovoltaic Units with Fresnel Lenses

The goal of this presented study was to determine the optimum parameters of secondary optical elements (SOEs) for concentrated photovoltaic (CPV) units with flat Fresnel lenses. Three types of SOEs are under consideration in the design process, including kaleidoscope with equal optical path design (KOD), kaleidoscope with flat top surface (KFTS), and open-truncated tetrahedral pyramid with spec...

Analysis Different MPPT Techniques for Photovoltaic System

In this paper we analysis different three MPPT techniques in photovoltaic system. These MPPT techniques are used to increase the efficiency of the photovoltaic system.

Material Optimization for Concentrated Solar Photovoltaic and Thermal Co-generation

We conducted an analytic study of concentrated solar photovoltaic and hot water co-generation based on various solar cell technologies and micro channel heat sinks. By co-optimizing the electricity generation and heat transport in the system, one can minimize the cost of the key materials and compare different tradeoffs as a function of concentration ratio or other parameters. Concentrated sola...
