According to foreign media reports, the latest experiment shows that the energy conversion rate of solar cells will increase significantly. In any traditional silicon-based solar cell, the overall efficiency has an absolute limit, partly because each photon of light can only produce one electron, even if this photon carries twice the energy required by the electron. But now, researchers have demonstrated a method of allowing high-energy photons to react with silicon to produce two electrons, which opens a door for new solar cells, which are much more efficient than ordinary solar cells. The research team of MIT and Princeton University published a paper in the "Nature" magazine pointed out that although the traditional solar cell theoretical solar conversion efficiency is about 29.1%, but the new methods they developed in the past few years may break through This limit may increase by several percentage points. The theory of this new technology has been proposed for decades, but six years ago, some members of the team experimented for the first time that this technology is feasible. The researchers say that the key to dividing the energy of one photon into two electrons lies in a class of materials called "excited states" called excitons. In these excitonic materials, the energy packets they possess travel like electrons in a circuit, but they have completely different properties from electrons. In this case, they experimented with a process called singlet exciton fission, which is how the energy of light splits into two independently moving energy packets. The "excited state" material first absorbs photons to form excitons, and then the excitons quickly undergo fission into two excited states, each excited state having half the energy of the original state. But a new problem arises, namely, how to couple two energies into silicon, and silicon is a non-excitatory material. To this end, the research team tried to couple the energy of the exciton layer into a substance called quantum dots, and it succeeded. But the researchers finally stated that the key issue now is how to fuse this newly-coupled quantum dot material into the chemical properties of silicon, and they are working hard to try and how to fuse in the best state.
