Furthermore it has shown in the past few years; the engineering improvement of perovskite formulation and fabrication routines has led to significant increases in the power conversion efficiency.
INTRODUCTION:
The term perovskite and perovskite structure often used interchangeably. Technically, perovskite is a type of mineral that was first found in the Ural Mountains. It named after Lev Perovski. A perovskite structure is any compound that has the same structure as the perovskite mineral. True perovskite composed of calcium, titanium and oxygen in the form CaTiO3. Meanwhile, a perovskite structure is anything that has the generic form ABX3. This section introduces perovskite solar cells, their structure, properties and their potential advantages over traditional silicon based these cells. Perovskite solar cells are type of those cells that uses perovskite material as light absorbing layer. Perovskite materials used in solar cells are typically hybrids, composed of organic cations. Such as; Methyl ammonium(MA+), Formamidinium (FA+), Inorganic elements, such as lead or tin.
