What is a solar cell?
A solar cell (also known as a photovoltaic cell or PV cell) is defined as an electrical device that converts light energy into electrical energy through the photovoltaic effect. A solar cell is basically a p-n junction diode.
What is a solar cell & how does it work?
Solar cell, any device that directly converts the energy of light into electrical energy through the photovoltaic effect. The majority of solar cells are fabricated from silicon—with increasing efficiency and lowering cost as the materials range from amorphous to polycrystalline to crystalline silicon forms.
What is a solar cell & a photovoltaic cell?
Solar Cell Definition: A solar cell (also known as a photovoltaic cell) is an electrical device that transforms light energy directly into electrical energy using the photovoltaic effect.
What is the basic principle behind the function of solar cell?
The basic principle behind the function of solar cell is based on photovoltaic effect. Solar cell is also termed as photo galvanic cell. The electricity supplied by the solar cell is DC electricity / current which is same like provided by batteries but a little bit different in the sense the battery is providing constant voltage.
What is a solar cell diagram?
The diagram illustrates the conversion of sunlight into electricity via semiconductors, highlighting the key elements: layers of silicon, metal contacts, anti-reflective coating, and the electric field created by the junction between n-type and p-type silicon. The solar cell diagram showcases the working mechanism of a photovoltaic (PV) cell.
How a solar cell is constructed?
Mainly Solar cell is constructed using the crystalline Silicon that consists of a n-type semiconductor. This is the first or upper layer also known as emitter layer. The second layer is p-type semiconductor layer known as base layer. Both the layers are sandwiched and hence there is formation of p-n junction between them.
