Solar cells made out of lead sulfide quantum dots could eventually offer a cheaper, more flexible alternative to ones made using silicon, but they are currently much less efficient. However, altering the chemical composition of quantum-dot solar cells offers a way of tuning them to reach higher efficiencies.
