Colloidal quantum dots: Performance boost next-generation solar cell technology
Researchers have created the most efficient solar cell ever made based on colloidal quantum dots (CQD). 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 a new study, the researchers demonstrate how the wrappers that encapsulate the quantum dots can be shrunk to a mere layer of atoms.
