To extract regulated power supply from the inputs of unregulated conditions, the zeta converter topology is the major application in the power electronics current mode operation. Zeta convertor can interfaced for high frequency application with a less switching stress and also it obtains regulated output voltage from the given input voltage which varies below and above output voltage, When compared with buck, boost, buck-boost and cuk converter, it gives non pulsating current with reduced settling time with adaptability. For different duty cycles and constant switching frequencies, the zeta converter with resistive load gives better results for buck and boost application.

The need for the unlimited source of energy has always been the area of concern as the efficiency of the available energy is still a major issue. As we have known that solar energy is abundantly available is nature but the use of solar energy is limited due the efficiency of the panels. The Photovoltaic efficiency is one the major areas for research and concern too if the aim for unlimited source of energy is to be realized. The paper presents a detailed study on the available and latest trends in solar cell technologies along with the present scenario of Solar PV efficiency through NREL data and the change and impact of price drop on solar PV panel. This paper can also be used a reference for new and budding researchers in the field of Solar cell technology.

The Extraction of photons radiation absorption is the best in the solar energy for photovoltaic cells working operations. In recent years’ research in Perovskite solar cell technologies have been an extremely enchanting. perovskite Organic-inorganic materials are in an expand growth in power conversion efficiency.In laboratory level the materials of Inorganic Perovskite solar cell have been tested but their power conversion efficiency is still finite. This paper work mainly focused to finding absorber layer optimum condition and also to simulate proposed structured perovskite solar cell. For simulations we used SCAPS-1D software simulator. The structure proposed of the solar perovskite cell employs resemblance with supplementary solar inorganic cells like CdTe,Cu (In, Ga) Se2 and CIGS.CH3NH3PbI3-xCl3 is layer absorber preowned as extremely efficacious absorberfor its great attention. The open circuit voltage for a condition is 1.112 V obtain and more than the efficiency value is 25%. The outcome of work, purpose of contacts like forepart and rear has a significant effect on top of the fill factor and efficiency also. By varied the parameter of thickness in layers of divergent bestoutcome has been attained and also shown quantum efficiency (QE) and I-V characteristics.
