Applying a layer of metal under the perovskites could enhance the light conversion efficiency of the semiconductive material by up to 250%.
The competition, silicon, the standard semiconducting material used in a host of applications – computer central processing units , memory and semiconductor chips, detectors, and solar cells – is an abundant, naturally occurring material. However, it is expensive to mine and purify.
This illustration from the Guo Lab shows the interaction between a perovskite material and a substrate of metal-dielectric material. The red and blue pairings are electron-hole pairs. Mirror images reflected from the substrate reduce the ability of excited electrons in the perovskite to recombine with their atomic cores, increasing the efficiency of the perovskite to harvest solar light.Guo noted, “No one else has come to this observation in perovskites.
In a solar cell, photons from sunlight need to interact with and excite electrons, causing the electrons to leave their atomic cores and generate an electrical current, Guo explained. Ideally, the solar cell would use materials that are weak to pull the excited electrons back to the atomic cores and stop the electrical current.
The lab was able to use a simple detector to observe the resulting 250 percent increase in efficiency of light conversion.
