Solar cells, also known as photovoltaic cells, convert sunlight directly into electricity through the photovoltaic effect. They are a key technology in renewable energy, offering a sustainable solution to reducing dependence on fossil fuels and minimizing environmental impact.

Solar Cells

Quantum confinement occurs when the dimensions of a material are reduced to a size comparable to the de Broglie wavelength of electrons, leading to quantized energy levels and altered electronic and optical properties. This phenomenon is crucial in the behavior of nanostructures such as quantum dots, nanowires, and thin films, impacting their applications in electronics and photonics.
