They can also withstand high levels of radiation and operate at extreme temperatures without significant changes in performance. Moreover, photocells do not require an external power source as they generate their own voltage through the absorption of light.
Photocell is also called an electron tube, photoelectric cell, electric eye, and phototube. This is an electronic instrument that is very vulnerable to incident radiation mainly light that is utilized for the generation or regulating the output levels of electric current.
Like miniature power plants, photovoltaic cells are designed to produce steady supplies of useful, electric power. From small solar cells on electronic calculators to completely photovoltaic roofs, their job is essentially to produce a constant supply of electricity that we can use to power electric appliances or store in batteries for later.
Photocells typically feature two electrical contacts placed on opposite ends of the photosensitive material, creating a pathway for current flow. When exposed to light, the photons absorbed by the photosensitive material cause electrons to gain energy and move more freely, reducing the material’s resistance.
A photocell has also been termed a sensor that can be utilized for the purpose of sensing light. The crucial characteristics of photocell sensors are uncomplicated usage, requires minimal power for operation, minimal size, and economical too.
A structure that, exposed to light, generates electric current constitutes a photovoltaic cell, or simply, a photocell. Photocells made of bulk semiconductors are referred to as photodiodes. Photovoltaic cells exposed to monochromatic light can, theoretically, achieve 100% efficiency converting radiation to electric energy.

Increasing photocell power by quantum coherence induced by external source
We show that photocell power can be substantially enhanced by quantum coherence in the model proposed by [M. O. Scully Phys. Rev. Lett. 104, 207701 (2010)]. Here coherence is induced by an external microwave drive. We show that although such coherence requires an extra energy input, the amount of extra input power can be much smaller than produced enhancement of the …
