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. This paper provides an overview of the current solar cell technologies and their drawbacks. 3 rd generation solar cells. We have the present energy resources are fossil fuels such as coal oil wood.

Nanotechnology nanowires photovoltaic cells renewable resources solar cells solar energy i. B current density voltage curves for control and 5 20 layer enhanced cells under one sun global air mass 1 5 am1 5g light. Making solar electricity cost efficient mass produced and available in many versatile forms by reducing the cost to under 1 watt. Nanotechnology applications under development.

These solar panels are extremely flexible and are sometimes even transparent due to the use of zinc oxide nanoparticles. Now a days with the growing population the energy demand is increasing day by day. A quantum dot qd enhanced solar cell design concept. 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. A solar cell is an electronic device which directly converts sunlight into electricity. 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.

Light shining on the solar cell produces both a current and a voltage to generate electric power. Developed proprietary process technology that makes it possible to produce 100x thinner solar cells 100x faster. Quantum dot solar cells are a variant of this approach but take advantage of quantum mechanical effects to extract further performance. Then it explores the research field of nano solar.

Researchers at flinders university have used phosphorene nanosheets to build low temperature perovskite solar cells.
