What is the application of "quantum dots" on solar cell?
Question:
Answer:
A team from Los Alamos National Laboratory found that quantum dots produce as many as three electrons from one high energy photon of sunlight. When today's photovoltaic solar cells absorb a photon of sunlight, the energy gets converted to at most one electron, and the rest is lost as heat. This could boost the efficiency from today's 20-30% to 65%. This work was reproduced one year later by an NREL team.
