Energy is an important material guarantee to meet the basic needs of human society and sustainable development. Due to the non-reproducibility of fossil energy and the global attention to the greenhouse effect, the effective use of solar energy is becoming the primary choice in most countries. Quantum dot solar cells have many advantages, such as low preparation cost, adjustable band gap and high theoretical conversion efficiency, and thus have great application potential in the field of solar energy conversion. However, the photoelectric conversion efficiency is still far lower than the theoretical conversion efficiency. It is urgent to explore the basic mechanism of low efficiency at the micro scale and provide guidance for the design of solar cells with high conversion efficiency. This problem poses a theoretical and technical challenge to modern research methods.
