Abstract
The presence of solar panels has increased in the last decade, making solar energy a prominent method of generating electricity in an environmentally friendly way. While most solar panels use silicon as their main semiconductor material because of its cost-effectiveness in manufacturing, its efficiency in converting light into electricity is lower than that of other sources. This is because silicon falls short due to its lack of flexibility and low light performance. Therefore, research into increasing the efficiency of solar panels has intrigued many scientists and opened up a broad field of inquiry. In this case, perovskites are at the forefront because of their flexibility, which improves charge-transport efficiency. We will be exploring how to build solar cells using photovoltaics like perovskites, specifically methylammonium lead bromide perovskites, and indium tin oxide as a transparent conductor. The method will incorporate a spin-coating process to fabricate a multi-layer solar cell and analyze its optical and electrical properties. Our first goal is to develop a working baseline procedure to construct the cells, after which we will explore variations on this baseline procedure to see how different changes impact the performance of the cell. In the future, we hope to control the thickness of the perovskite layer and even the perovskite concentration in the precursor solution. Moreover, we would like to examine the effect of varying ratios of methylammonium to see how it impacts the efficiency of the solar cell and why this is occurring.
