What happens to the UV photons that strike the photovoltaic cell but do not take part in the photo electric efect, do thay reflect? apparently the best comercial solar cells are only 24% eficiant.
The photoelectric effect is a phenomenon in which electrons are emitted from a material when it is exposed to electromagnetic radiation, such as light.
Photons are particles of light that carry energy. They have both wave-like and particle-like properties, and are the fundamental unit of electromagnetic radiation.
When photons of sufficient energy strike a material, they transfer their energy to electrons in the material. This can cause the electrons to be emitted from the material, resulting in the photoelectric effect.
The energy of a photon is directly related to the energy of an emitted electron. The more energetic the photon, the more energy it can transfer to the electron, resulting in a higher energy electron being emitted.
The photoelectric effect is used in a variety of technologies, such as solar panels and photodetectors. It is also the basis for the operation of devices such as photocells and photomultiplier tubes, which convert light into electrical signals.
