Nano solar cells ppt.

We have the present energy resources are fossil fuels such as coal oil wood. 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. Cost reduction by nano nanotechnology reduces installation cost. Now a days with the growing population the energy demand is increasing day by day.

Because of nanotechnology solar power is cheaper than burning coal. 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. 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.

Researchers at flinders university have used phosphorene nanosheets to build low temperature perovskite solar cells. Nanotechnology nanowires photovoltaic cells renewable resources solar cells solar energy i. Power solar sheets helps to reduces cost of solar cells cheaper power sheets are made by nanosolar companies. It commonly uses nano sized particles.

These cells use organic and inorganic molecules to combine the excitons or the electron hole pair to create current. Nanotechnology applications under development. 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. These solar panels are extremely flexible and are sometimes even transparent due to the use of zinc oxide nanoparticles.

Solar cells but the most promising application of nanotechnology is the reduction of manufacturing cost. Utilizing nanotechnology in inexpensive solar cell would help to preserve the environment. Infrared plastic solar cell scientists have invented a plastic solar cell that can turn the suns power into electrical energy even on a cloudy day. Quantum dot solar cells are a variant of this approach but take advantage of quantum mechanical effects to extract further performance.

3 rd generation solar cells. The new material uses nanotechnology and absorbs the infrared part of the sun s energy. Then it explores the research field of nano solar.
