Abstract:

Over the last decades development of highly efficient photovoltaic devices using small organic and inorganic photovoltaic materials, specifically, lead halide perovskite, gain an attention in solar cell industry. The surface morphology of these material plays a vital role in their performance and stability. In this project, we will investigate how the surface morphology of these materials affects photocurrent efficiency. We will analyze the surface morphology using customized Raman microscopy and correlate it to their photocurrent efficiency by detecting photoluminescence intensity. Understanding the correlation between surface morphology and photocurrent efficiency of these materials will shed light on developing highly efficient and robust next-generation photovoltaic materials and formulating new strategies in thin-film processing.
