Certain experimental investigation on methylammonium lead iodide based perovskite solar cells

Abstract

Over the last five decades, biosphere has been sacrificed as a result of the tremendous evolution of modern technologies in production and energy consumption. Non-renewable energy resources such as coal, natural gas, and oil are no longer sufficient to meet current and future energy demands. As a result, renewable energy has gained attention because it is efficient, environmental friendly, sustainable and widely available. Among several renewable energy resources, solar energy is the most abundant source of energy, with 1.4 x 1016 kWh/year of sunlight providing approximately more than 100 times the total fossil fuel resources. However, before deploying solar photovoltaic technologies in the real world, it is more important to understand their physics and working potential. The work mainly focuses on the various components and ambient process conditions for the simulation and fabrication of methylammonium lead iodide (MAPbI3) based perovskite solar cells. newlineThis study investigates the process involved in the fabrication of mono-crystalline silicon solar cells, including wafer cleaning, optical photolithography and metallization. At present silicon is the most widely used material in solar photovoltaic cells, accounting for approximately 95 % of total photovoltaic manufacturing. Nevertheless, they cannot overcome the Shockley-Queisser efficiency limit of 30 %, less favourable band-gap 1.1 eV, limiting absorption properties and also the manufacturing process is time-consuming and costly. Hence, in this study, a perovskite-based solar cell is attempted as an alternative technology for silicon-based solar cell in order to address the aforementioned challenges. newline newline
