Nano solar cells ppt.

Quantum dot solar cells are a variant of this approach but take advantage of quantum mechanical effects to extract further performance. 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. 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. These cells use organic and inorganic molecules to combine the excitons or the electron hole pair to create current.

This paper provides an overview of the current solar cell technologies and their drawbacks. Power solar sheets helps to reduces cost of solar cells cheaper power sheets are made by nanosolar companies. Utilizing nanotechnology in inexpensive solar cell would help to preserve the environment. 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.

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. These solar panels are extremely flexible and are sometimes even transparent due to the use of zinc oxide nanoparticles. Researchers at mit have developed a method to manufacture larger defect free sheets of graphene for use in lightweight solar cells.

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. 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. We have the present energy resources are fossil fuels such as coal oil wood. It commonly uses nano sized particles.

Then it explores the research field of nano solar. Researchers at flinders university have used phosphorene nanosheets to build low temperature perovskite solar cells. Because of nanotechnology solar power is cheaper than burning coal. Cost reduction by nano nanotechnology reduces installation cost.

Nanotechnology nanowires photovoltaic cells renewable resources solar cells solar energy i. Reducing production cost from 3 a watt to 30 cents only. Solar cells but the most promising application of nanotechnology is the reduction of manufacturing cost.
