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) ...

The electrical performance of a photovoltaic (PV) silicon solar cell is described by its current–voltage (I–V) characteristic curve, which is in turn determined by device and material properties. In this study, an investigation of the performance and device parameters of photovoltaic single crystalline silicon (Si) solar cell of the construction n+pp++ PESC (Passivatted Emitter Solar Cell) at d...

BACKGROUND This paper examines the cost and benefits, both financial and environmental, of two leading forms of solar power generation, grid-tied photovoltaic cells and Dish Stirling Systems, using conventional carbon-based fuel as a benchmark. METHODS First we define how these solar technologies will be implemented and why. Then we delineate a model city and its characteristics, which will b...

Recent progress in the development of nanostructured inorganic solar cells is reviewed. Nanostructuring of inorganic solar cells offers the possibility of reducing the cost of photovoltaics by allowing smaller amounts of lowergrade photovoltaic semiconductors to be used. Various fabrication methods used to nanostructure traditional photovoltaic semiconductors are detailed and the performance of...

Photovoltaic method is very popular for generating electrical power. Its energy production depends on solar radiation on that location and orientation. Shadow rapidly decreases performance of the Photovoltaic system. In this research, it is being investigated that how exactly real-time shadow can be detected. In principle, 3D city models containing roof structure, vegetation, thematically diffe...

To optimize the performance of polymer solar cells, various techniques have been developed and reported from various research fields. The introduction of processing additives in the polymer : PCBM bulkheterojunction solution is one of the efficient strategies used to improve the cell performance. Although numerous solvents have been presented as processing additives, an appropriate processing a...

As worldwide demand for fossil fuels depletes reserves, scientists are increasingly focused on generating alternative energy— especially if it can be produced cleanly and inexpensively. Hydroelectric, solar, wind, nuclear, and biomass technologies are replacing coal, oil, and natural gas. Many of these new technologies have similar costs. Yet the availability of materials or existing infrastruc...

Hybrid system based on photovoltaic is considered an effective option to electrify remote and isolated areas far from grid. This is true for areas that receive high averages of solar radiation annually. Using diesel generator as a standby source will make utilization of hybrid systems more attractive. An economic feasibility study and a complete design of a hybrid system consisting of photovolt...
