How Do Nanomaterials Enhance Solar Cell Efficiency?
Nanomaterials contribute to solar cell efficiency in several ways:
Light Absorption: Nanomaterials can be engineered to have a high absorption coefficient, enabling them to absorb more sunlight and generate more charge carriers. Charge Transport: Materials like carbon nanotubes and graphene facilitate faster and more efficient charge transport, reducing energy losses. Surface Area: The high surface area of nanomaterials increases the active area available for light absorption and charge separation. Bandgap Engineering: Quantum dots and other nanomaterials can be tailored to have specific bandgaps, optimizing the absorption of different wavelengths of light.
