Making progress towards lead free efficient perovskite solar cells: A DFT study

The capacity to maintain a steady supply of energy is crucial for a nation's progress. Solar power is the most well-known contender for an alternative energy source after fossil fuels. We need more electric power for our increasing population. Natural resources are very limited in our country for electrical power generation. So, we must shift toward renewable energy which is cost effective and eco-friendly. The next generation of cost-effective solar module technology is solar cells, which has set new standards for renewable energy. As part of ambition to produce 10% of electricity from renewable sources, our government has taken on a total of 19 solar power projects totaling 1070 MW capacity. That is why solar cells are getting noticeable attention to the power generation companies in recent year.

The proposed research is related to nontoxic solar cell materials. Solar panel efficiency is generally around 15-20%. We aim to study the change in different properties of the perovskite solar cell materials to increase the efficiency of photovoltaic cells. Density functional theory (DFT) based simulation will be used to understand the change in the different properties of the nontoxic perovskite materials for solar cell.
