Novel process can improve quantum dots for solar cells

Using a novel molten droplet method to make lava dots out of zinc sulphide, cadmium sulphide and zinc selenide, hollow particles can exceed some performance metrics of quantum dots in a solar-cell test device.

State) have created the most efficient solar cell ever made based on colloidal quantum dots (CQD).

The discovery is reported in the latest issue of Nature Materials.

Quantum dots are nanoscale semiconductors that capture light and convert it into an energy source. Because of their small scale, the dots can be sprayed on to flexible surfaces, including plastics. This enables the production of solar cells that are less expensive to produce and more durable than the more widely-known silicon-based version. In the work highlighted by the Nature Materials paper, the researchers demonstrate how the wrappers that encapsulate the quantum dots can be shrunk to a mere layer of atoms.
