One potentially cost-effective approach to harvesting solar power from space is the use of thousands of individual robots moving in formation, each with a piece of solar panel attached, to form a solar panel array. In previous work, we demonstrated an algorithm that treats a group of robots as a 1-dimensional cellular automaton, which is able to establish formations defined by a single mathemat...

Physical integration of a Ag electrical contact internally into a metal/substrate/microstructured Si wire array/oxide/Ag/electrolyte photoelectrochemical solar cell has produced structures that display relatively low ohmic resistance losses, as well as highly efficient mass transport of redox species in the absence of forced convection. Even with front-side illumination, such wire-array based p...

A new method of array configuration for solar tracking photovoltaic (PV) devices is proposed. By analyzing the affecting factors of shadows, a calculation model of PV cell panels’ shadow in the sunlight is structured. And the variation rule of shadows in a year is founded by simulation program. Then a spacing calculation method of the solar tracking device array is proposed. The experiment resu...

Large-sized titanium dioxide (TiO2) nanotube arrays with an outer diameter of approximately 500 nm have been successfully synthesized by potentiostatic anodization at 180 V in a used electrolyte with the addition of 1.5 M lactic acid. It is found that the synthesized large-diameter TiO2 nanotube array shows a superior light scattering ability, which can be used as a light scattering layer to si...

A new Self-Organizing Learning Array (SOLAR) system has been realized in software. SOLAR is capable of handling a wide variety of classification problems. It has a regular array structure with sparsely interconnected computing elements and local learning rules. Unlike artificial neural networks, this structure scales well to large systems capable of solving complex pattern recognition and class...

As per the present scenario lot of power shortages are there all over the world especially country like India the grid transferring problem is also high. Almost the power from the fossil fuels is becoming so less. There is increasing demand for the use of power from renewable based energy sources such as solar, wind, biomass, tidal etc which does not cause any damage to the environment. Unlike ...

To convert solar energy more viable, the efficiency of solar array systems should be maximized. An easier approach to maximizing the efficiency of solar array systems is Maximum Power Point Tracking (MPPT). MPPT is used in photovoltaic (PV) systems to maximize the output power of photovoltaic array, irrespective of the irradiation and temperature conditions. Many conventional MPPT fails to atta...
