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...

In this paper, the morphology of chemically etched silicon with various concentration  is reported. The surface of Silicon (100) has pyramidal structures which can be used for anti-reflection applications in solar cells. Pyramidal structures can capture incident sun light therefore can enhance the efficiency of silicon solar cells. The structure of silicon pyramid was studied using scanni...

Silicon nanowire (SiNW) arrays were produced by electroless method on polycrystalline Si substrate, in HF/ AgNO3 solution. Although the monocrystalline silicon wafer is commonly utilized as a perfect substrate, polycrystalline silicon as a low cost substrate was used in this work for photovoltaic applications. In order to study the influence of etching time (which affects the SiNWs length) on d...

Dye-sensitized solar cells present promising low-cost alternatives to the conventional Silicon (Si)-based solar cells. The counter electrode  generally consists of Pt deposited onto FTO plate. Since Pt is rare and expensive metal, nanostructured carbonaceous materials have been widely investigated as a promising alternative to replace it. Carbon nanotubes  have shown significant properties such...

The effect of single and double-layer anti-reflective coatings on efficiency enhancement of silicon solar cells was investigated. The reflectance of different anti-reflection structures were calculated using the transfer matrix method and then to predict the performance of solar cells coated by these structures, the weighted average reflectance curves were used as an input of a PC1D simulation....
