Quantum dots will be used as a replacement for pigments owing to their outstanding optoelectronic properties in solar cells. Such nanoparticles, based on their shape and scale, may absorb various wavelengths and become agitated, and then release absorbed energy in the form of radiation from another wavelength or original wavelength. Simply stated, the key characteristic of such nanoparticles is the fact that they are fluorescent. The basic denominator of such nanoparticles is their special optical properties. Light emitting nanoparticles, such as quantum dots, gold or silver nanoparticles and fluorescent nanofibers, are commonly used to improve the performance of solar cells. Meanwhile, the light emitting nanoparticles got a lot of coverage owing to their very fascinating properties in the area of light absorption and reflection. Nanomaterials have been developed and manufactured in numerous ways for diverse uses since the advent of nanotechnology in the last decades. In the meantime, Iran ranks seventh in mine resources.ĥ.1 Light emitting nanoparticles a reasonable way to improve the performance of a solar cell Iran has a strong potential to get this energy supply close to the equator. Figure 1 shows the influence of solar energy in the World. Since the underlying essence of green energies, like solar energy, is mostly local and distributed, so if it is not feasible to utilize the global grid, it is reasonable that the usage of such resources would be decentralized so spread, rather than centralized output, will be more justifiable. This resource came to expected that, with the elimination of barriers, the solar power potential of built power plants would hit more than 500 GW by 2020. Todays, about 178 GW of electricity supply has produced by solar energy. Currently, owing to the need to harvest solar energy, numerous forms of solar power production systems have been developed in different countries with the correct capacity for solar radiation, so that their electricity is transmitted to the national grid. The production of this energy is therefore of considerable significance.
The sunlight that the Sun reflects on the planet every hour is greater than the entire resources that the people of the world eat in a year.

Solar energy, the world’s biggest energy source, as a renewable energy source, inexpensive and free emissions, has a special role in energy supply. Attention to alternative energy sources such as solar energy, wind, hydro and tides, and biomass from fuel cells and hydrogen is of great interest in industrial and science communities today. Owing to the dwindling fossil fuel supplies and the environmental consequences of their usage and the rising greenhouse gas emissions that have warmed the earth, discovering a new source of renewable, efficient and biocompatible energy is a problem confronting scientists and researchers today. For this purpose, nanotechnology applications have been proved in a broad variety of areas, such as physics, chemistry, biological sciences, materials sciences, electronics and energy sciences. At these nanometer measurements, materials can exhibit new properties that are absent or low in their bulk. Nanotechnology is an interdisciplinary area of research, engineering and development that encompasses nanoscale materials from 1 to 100 nanometers.
