Solar Photovoltaic (PV) has emerged as a major contender to serve as an alternative energy source and is currently playing a leading role in supporting the existing conventional power generation systems. Several solar PV systems require a high gain front end dc-dc converter. Conventional dc-dc converters can offer limited gain and their efficiency drops as the gain requirement increases. This p...

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...

This paper describes synthesis of In2S3 nanoparticles by sonochemistry method and their application to enhance solar cells performance which In2S3 nanoparticles work as co-sensitizer for the first time. In2S3 is a narrow band gap semiconductor (2 eV) with conduction band higher than TiO2. Therefore it can transfer electron to the conduction band of TiO2. The effect of different parameters such ...

using photovoltaic systems is gradually expanded by increasing energy demand. abundance and availability of this energy, has turned to one of the most important sources of renewable energy. unfortunately, photovoltaic systems have two big problems: first, those have very low energy conversion efficiency (in act between 12 and 42 percent under certain circumstances). second, the power produced b...

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...

Kesterite Cu2ZnSn(SxSe1−x)4 has tunable band-gap values in the range 1 to 1.5 eV depending upon Sulphur/Selenium stoichiometry. We analyze proposed tandem configuration of kesterite absorber family using SCAPS-1D for device performance. Pure sulphide Cu2ZnSnS4 (CZTS) bandgap is utilized as top cell and a sulpho-selenide (CZTSSe) 1.1 bottom stacked configuration. utilize script file capability S...
