Abstract

The silicon based solar cells are expensive, and also said to have limited power conversion efficiency. Though a lot of organic, inorganic and organic-inorganic hybrid solar cells were developed, they could not sustain in long run. This has open doors for the development the ferroelectric based solar cells/photovoltaics. Because the ferroelectric based photovoltaics show high open circuit voltage, short circuit current/current density, unlimited power conversion efficiency, tunable bandgap, high polarization properties, etc. The main reason to shift the focus from semiconductor solar cells is,the ferroelectrics are said to be stable under changing environmental conditions. In addition, such materials help to develop thinner solar cells devices with low cost. Hence, an attempt has been made to understand the photovoltaic response of ferroelectric lead zirconate titanate (PZT). In this paper, we report the review on the photovoltaic properties of PZT films. The literature was collected from various internet sources.

Summary

Introduction

Among the sources of renewable energy, presence of polarization when the applied ac sunlight/solar energy is one of the significant and electric field is reduced to zero. Photovoltaics: Devices that is capable of continuously, it is worth to use the renewable converting the light (photons) into electricity energy sources ( solar energy) to (electrons). Energy into electrical energy, several solar cells Photo-ferroelectrics: Ferroelectrics that is capable and photovoltaic devices have been developed. Of converting the light (photons) into electricity Open Circuit Voltage: It is the voltage developed across a solar cell when there is no flow of current www.rspsciencehub.com i.e. the terminals of a solar cell are open.
