How Do Quantum Dots Enhance Solar Cell Efficiency?
Quantum dots are semiconductor nanoparticles that can be tuned to absorb different wavelengths of light by adjusting their size. This tunability allows them to harvest a broader spectrum of solar energy compared to traditional materials. Moreover, quantum dots have the potential to achieve multiple exciton generation (MEG), where a single photon generates multiple electron-hole pairs, significantly boosting the efficiency.
