How Does Nanotechnology Improve Solar Cell Efficiency?
Nanotechnology enhances solar cell efficiency in several ways:
Light Absorption:Nanomaterials such as quantum dots and plasmonic nanoparticles can significantly increase light absorption by trapping light more effectively within the cell. Carrier Collection: Nanostructures like nanowires and nanotubes offer a direct path for electrons, reducing recombination losses and enhancing carrier collection. Tunable Bandgaps:Quantum confinement effects in nanomaterials allow for the tuning of bandgaps to better match the solar spectrum, thereby improving efficiency.
