Investigation and analysis of the performance of solar cells based on nanostructures

With the rapid growth of energy consumption in the world and the limitations of fossil resources, attention to renewable energies as a fundamental solution for sustainable energy supply in the future has increased significantly. Among them, solar energy has opened a special place among renewable energy sources due to its abundance, cleanliness and ability to be exploited on various scales. Solar cells, as the main means of converting solar radiation energy into electrical energy, have made acceptable progress in recent years. However, the limited number of conventional solar cells, especially conventional silicon cells, remains a major challenge in this technology. In recent years, advances in nanotechnology and the emergence of nanoscale structures have spurred new approaches to improving solar cells. Nanostructures play an important role in increasing efficiency and reducing energy losses by enabling fine-tuned control of light behavior, increasing the effective light path, and improving minority carrier collection. In this article, the performance of solar cells based on nanostructures is thoroughly investigated and analyzed. First, the theoretical foundations of solar cells and structural limitations are stated, then the role of nanoparticles, nanowires, and structural layers in improving light absorption and increasing efficiency in solar cells is summarized.
