In photo voltaic cells there copper plate and on this plate there is a layer of cupprous oxide layer.
On this cuprous oxide layer again there is a thin layer of silver.When light having the threshold frequency is incident on the silver layer it is focussed on the cuprous oxide layer and the electrons on this layer are ejected out and pushed on to the copper plate.Here the copper plate acts as an anode and hence the flow of electrons takes place which constitutes the electric current.
The flow of electric current can be observed by coonecting a galvanometer in the circuit attached from silver layer to copper plate.
The use of silver layer is that it will stop the ejection of electrons out from it.
And this is the photo cell used most widely.It costs 28-30 Rs

How does the photovoltaic cell work?
Photovoltaic energy is the conversion of sunlight into electricity. A photovoltaic cell, commonly called a solar cell or PV, is the technology used to convert solar energy directly into electrical power. A photovoltaic cell is a nonmechanical device usually made from silicon alloys. When light strikes these silicon alloys, it frees electrons which can be collected onto attached conductive plates.
What are some factors that would affect the electrical production of a photovoltaic cell?
darkness. it needs light to work
What is conversion efficiency of photovoltaic cell?
10-15%
Which tool converts sunlight into electricity?
Photovoltaic cell
What is the definition of photovoltaic solar cells?
Photovoltaic cells are transducers that convert light to electrical potential (voltage). Solar photovoltaic cells are photovoltaic cells that are specifically designed to work with sunlight.
What is the device that turns solar energy into electrical energy?
A photovoltaic cell.A photovoltaic cell.A photovoltaic cell.A photovoltaic cell.
