Quantum Dot Solar Cells

Next-generation solar cells using quantum dots achieving record 16.6%^[1] efficiency with theoretical potential exceeding 30%. Tandem architectures with perovskite-silicon combinations demonstrate 29.15%^[1] efficiency in laboratory conditions.

How It Works

Quantum dot solar cells use semiconductor nanocrystals that can be tuned to absorb specific wavelengths of light by controlling particle size. Advanced tandem cell architectures stack multiple photovoltaic layers to capture broader spectrum ranges, with perovskite-silicon combinations achieving highest efficiencies. Quantum confinement effects enable precise bandgap engineering for optimal light absorption.
