Executive Summary : | Perovskite material based solar cells have made significant progress and it has been establish that they can achieve, power conversion efficiency of more than 25%. Structural growth in nanotechnology have a great potential in the evolution of the structure of perovskite solar cell to enhance in their performance, and further enabled extension into flexible devices. In this regard, BiFeO3 based nanomaterials; thinfilm and ceramic shows the consistent results for photovoltaic applications in coalition with the electric and magnetic properties. Recent research claims that power conversion efficiency of ferroelectric photovoltaic devices can exceed the Shockley-Queisser limit. Additionally high remnant polarization ~100 μC/cm2 , narrow band gap (~2.1 eV) and crystalline nature make it a potential candidate for photovoltaic technology. However, the unique and intriguing properties of reduced graphene oxide (rGO) such as crystalline structure, electronic properties, large surface area and tunability of surface properties makes it a desirable candidate for suppression of recombination of photogenerated charge carriers. rGO is considered as a potential candidate to reduced band gap and enhance surface area for hybrid composite to enhance the optical properties of the material. rGO is a useful loading material because it has the ability to act as a reservoir of electrons to shuttle the electrons generated from the polarised material. Therefore this composite exhibits ferroelectric properties coupled with large active sites with a shorter optical band gap which can yield desirable results for photovoltaic applications. |
