INTERFACE ENGINEERING OF HIGHLY EFFICIENT PEROVSKITE SOLAR CELL

Abstract

Energy has been the central building piece of each phase of human improvement.Various sources of energy has been explored since ages. In recent centuries huge steps have been taken in the form of exploitation of conventional energy sources as most of the nonrenewable energy sources are at the edge of elimination. Search of renewable energy sources is needed for the sustainable development. On earth main energy source is Sunlight which has been used as generation of power from many years. Biggest challenge comes in the form of cost of per unit power utilization, since huge cost is needed in fabrication of photo voltaic cells based on semiconductors. In most recent couple of decades there has been an extraordinary research going ahead to create sun powered cells that can give practically identical execution and more open cost. Today an enormous piece of research society is chipping away at inorganic and organic based sun powered cells that can be made with method based on solution technique. There has been a blast being developed of solar cell based on hybrid perovskite. There are the materials having structure as structure of calcium titranate which having a inorganic cation and inorganic cation. These materials have properties, for example, great optical absorption band gap like that of semiconductors. A high development in e ciency have been shown in Perovskite based solar cell. In very recent years it reaches from 3% to 22%. Stability of these kind of solar call is a big challenge since degradation of perovskite materials happen in high temperature, humidity and insolation quickly. These are the greatest hindrance in the way of solar cell based on perovskite materials. Large number of groups around the world are working to observe the explanation behind this disintegration. One of the approaches to get the kinetics of device when the degradation process happen and henceforth looking through the di erent electrical parameters of the device which changes as the degradation of solar cell happen
