How Do Nanomaterials Enhance Conversion Efficiency?
The unique properties of nanomaterials, such as their high surface area to volume ratio, quantum effects, and tunable optical properties, contribute to their enhanced performance in energy conversion devices. For example, in photovoltaic cells, nanomaterials can create multiple excitons per photon, leading to higher conversion efficiencies. In thermoelectric devices, nanostructuring can reduce the thermal conductivity while maintaining or enhancing electrical conductivity, leading to higher thermoelectric figures of merit.
