The solar cell industry is growing day by day due to rising prices of fossil fuels, the problem of global climate change and increasing demands of clean, efficient and low cost renewable energy. But the manufacturing cost of solar cells is an important aspect. However, thin film solar cells decreased the cost of the cell by reducing the thickness but trapping of enough light becomes crucial in these cells. By incorporating plasmonic nanostructures of different materials, configurations and geometries in thin film solar cell design, researchers measured an enhanced photocurrent attributed to the increased trapping of light scattered into a thin-film solar cell by metal nanoparticles excited at their surface Plasmon resonance and overall efficiency enhancement of about 8% have been achieved. Now, we are looking to design plasmonic solar cells with more efficiency in the photovoltaic industry.
