Abstract
In this tool, we build a simple and costeffective tools to extract the photovoltaics parameters form light current-voltage and EQE data. The tools is published as the Web App using the streamlit library. The tools contains two different parts, (1) Extraction of the I-V parameters using the raw I-V data, and this will allows us to to know th photovoltaics parameters of the devcies within a second, (2) part is the cutting-edge EQE-Jsc and Voltage-Loss Analysis Calculator! This advanced tool empowers you to calculate integrated Jsc and perform voltage-loss analysis effortlessly. The links of these web app as follows: https://ivparameters.streamlit.app/, https://voltagelossanalysis.streamlit.app/.
Bio
Mr. Rakesh Suthar is a graduate student working at the department of energy science and engineering, Indian Institute of Technology Delhi (IIT-Delhi), India. His current research focuses on the device physics of next-generation photovoltaics, with an emphasis on experimental-oriented machine-learning approach for developing efficient organic solar cells and photodetectors.
Dr. Supravat Karak is working as an Associate professor at the Department of Energy Science and Engineering, Indian Institute of Technology Delhi. Fabrication of organic and hybrid molecule based photovoltaic devices and understanding the fundamental photo-physics of such new class of material systems to improve their performance both in terms of efficiency and lifetime, are his primary research interests. He also works on nano and 2D materials for energy harvesting applications.
