Utilizing nanotechnology in inexpensive solar cell would help to preserve the environment. Introduction nano technology might be able to increase the efficiency of solar cells but the most promising application of nano technology is the reduction of manufacturing cost. Nanocrystal solar cells are solar cells based on a substrate with a coating of nanocrystals the nanocrystals are typically based on silicon cdte or cigs and the substrates are generally silicon or various organic conductors. These cells use organic and inorganic molecules to combine the excitons or the electron hole pair to create current.

Then it explores the research field of nano solar. This paper provides an overview of the current solar cell technologies and their drawbacks. Nanotechnology nanowires photovoltaic cells renewable resources solar cells solar energy i. Quantum dot solar cells are a variant of this approach but take advantage of quantum mechanical effects to extract further performance.

Because of nanotechnology solar power is cheaper than burning coal. Reducing production cost from 3 a watt to 30 cents only. It commonly uses nano sized particles. Researchers at mit have developed a method to manufacture larger defect free sheets of graphene for use in lightweight solar cells.

It uses the 1st generation solar cells which absorbs energy efficiently. The new material uses nanotechnology and absorbs the infrared part of the sun s energy. We have the present energy resources are fossil fuels such as coal oil wood. Structure of presentation intruduction solar pv cells drawback of solar pv cells nano technology in solar cells applications of nano solar cells comparision conclusion 3.

Solar cells but the most promising application of nanotechnology is the reduction of manufacturing cost. Future of nano solar cells there is huge demand for use of renewable resources due to its low carbon footprint with solar energy is leading the race as a viable alternative for fossil fuels low efficiency and expensive silicon wafers makes nano solar cells the future of solar panels along with silicon and cigs other materials are. Some recent developments in nanotechnology have opened up new avenues for more relevant inorganic solar cells produced by new photovoltaic conversion concepts and effective solar energy harvesting. Now a days with the growing population the energy demand is increasing day by day.

Researchers at flinders university have used phosphorene nanosheets to build low temperature perovskite solar cells. These solar panels are extremely flexible and are sometimes even transparent due to the use of zinc oxide nanoparticles. Power solar sheets helps to reduces cost of solar cells cheaper power sheets are made by nanosolar companies.
