![]() ![]() Solar energy has been produced from the sun and eliminates the hassle, confusion and cost of fueling a generator powered by gas or diesel. ![]() Fossil fuels create toxic emissions that influence the quality of water, air and soil and are concerned about global warming, another justification for choosing solar energy. Amongst which, residential solar is among the most accessible and abundant. electricity sources as the cost of renewable energy begins to fall. Many households are converting to pure, renewable. The alternative source of energy is renewable energy. It is predicted that in the next 200–300 years, fossil fuels, particularly oil, will be depleted. Owing to the rapid increase in industrialization and population, global energy demand is at an extreme, whereas traditional fossil fuels such as coal, natural gas and oil, etc. Special emphases are given to solar cells based on nanostructure and nanodevices. This paper reviews recent advances on development of nanotechnology in the solar energy devices. Improved materials efficiency and reduced manufacturing costs are just two of the real economic benefits that nanotechnology already brings these fields. Nanotechnology will bring significant benefits to the energy sector, especially to energy storage and solar energy. devices various approaches was intended but nanotechnology, a combination of chemistry and engineering, is viewed as new candidate for clean energy applications. In this challenge, solar energy production is rapidly becoming a vital source of renewable energy being developed as an alternative to traditional sources of power. One of the biggest challenges for mankind in the century of 21 is use of alternative sources for non-renewable, limited fossil fuels that tremendously contribute on the problem of global warming.
