in this paper, a novel control method for photovoltaic converter connection to the national gridis presented, so in addition to the injection control by solar arrays to the grid, this method cancompensate reactive power and harmonics in the load current. the system will be connected inparallel between the grid and load. the proposed system supplies all load power consumption(including active po...

Nanowires (NWs) are recently used in several sensor or actuator devices to improve their ordered characteristics. Silicon nanowire (Si NW) is one of the most attractive one-dimensional nanostructures semiconductors because of its unique electrical and optical properties. In this paper, silicon nanowire (Si NW), is synthesized and characterized for application in photovoltaic device. Si NWs are ...

Today, due to qualitative growth and scientific advances, energy, especially electricity is increasingly needed by human society. One of the almost endless and pure energy which have been paid attention over the years is the solar energy. Solar cells directly convert solar energy into electrical energy and are one of the main blocks of photovoltaic systems. Significant improvement has been made...

This paper deals with the optical design of a photovoltaic solar concentrator composed by two squared reflection mirrors. The optical configuration of the device, is based on the Cassegrain telescope and designed in order to maximize the fill factor over the irradiated area and by providing an easily manufactured shape. The collection unit has been simulated and optimized by a ray tracing metho...

A bifunctional compound 1 was designed and synthesized, in which the donor-π-conjugated-acceptor-cyanoacrylic acid configuration is suited for DSSC, while the tetraoxa-azacrown (donor) part also acts as the recognition unit for e.g. Ca(2+) and the output of DSSC is utilized as signal transduction, demonstrating a new recognition concept using DSSC.

fuzzy logic has been developed over the past three decades into a widely applied techinque in classification and control engineering. today fuzzy logic control is one of the most important applications of fuzzy set theory and specially fuzzy logic. there are two general approachs for using of fuzzy control, software and hardware. integrated circuits as a solution for hardware realization are us...

Solar cell is known as a sustainable and environment friendly source of energy in nature. It converts sunlight directly into electricity with zero emission and also without side-effects on the environment. But, solar cells have optical and mechanical defects which include the type of micro crack, the size of crack, and the noise from electrical or electromechanical interference during the image...
