To realize such ultraefficient solar cells, it requires that the excess energy of excited “hot” carriers is captured for power generation by reducing the rate of, or even preventing, carrier cooling. It has been known that phonon bottleneck effects (PBE) play the most decisive role in reducing the carrier thermalization rate.

Typical photovoltaic solar panels consist of a configuration of 32 to 72 solar cells connected in a series. This makes solar panels sensitive to partial shading. Shaded solar panel cells interrupt the energy flow in the grid, forcing other cells to work harder to compensate for the loss. Electrons under the shaded solar cells are not moving.
