Nanotechnology is extremely versatile and has a broad range of potential uses. Since a few years ago, nanotechnology has been widely used to support innovative research methods. Analysts are interested in this subject to nurture novel materials and applications despite this. Nan science has evolved into a distinctive and innovative discipline of specialized movement. The extraordinary design of nanoscale technology and the special properties of nanostructures are some of the factors. The solar cell industry has recently seen rapid expansion as a result of the rising demand for environmentally friendly energy sources and worries about global environmental change. Cost must be taken into account for any solar invention. To create solar cells for a large-scale energy age would be both prohibitively expensive and inherently inefficient. In any case, it is expected that nanotechnology will improve, opening the door to the creation of solar cells that are less expensive and slightly more effective. Nanotechnology has significantly advanced the study of solar energy. Nanotechnology, the most sophisticated invention produced by mankind to date, has an impact on all energy systems with its methods for managing energies, particularly solar energy. This essay discusses current advances in solar cell-related nanotechnology and proposes the use of traditional solar PV cells for display. For the mass power era, nanotubes and quantum dots may assist lower the cost of PV cells and modules while also increasing the effectiveness of cell switching in nanotech solar cells.
