6 FAQs about [Working chemistry of photovoltaic cells]
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 working principle of a photovoltaic cell?
Working principle of Photovoltaic Cell is similar to that of a diode. In PV cell, when light whose energy (hv) is greater than the band gap of the semiconductor used, the light get trapped and used to produce current.
How do photovoltaic cells work?
Photovoltaic cells are made of special materials called semiconductors like silicon, which is currently used most commonly. Basically, when light strikes the panel, a certain portion of it is absorbed by the semiconductor material. This means that the energy of the absorbed light is transferred to the semiconductor.
What is the working principle of a solar cell?
Working Principle: The solar cell working principle involves converting light energy into electrical energy by separating light-induced charge carriers within a semiconductor. Role of Semiconductors: Semiconductors like silicon are crucial because their properties can be modified to create free electrons or holes that carry electric current.
What is the photovoltaic process?
The photovoltaic process bears certain similarities to photosynthesis, the process by which the energy in light is converted into chemical energy in plants. Since solar cells obviously cannot produce electric power in the dark, part of the energy they develop under light is stored, in many applications, for use when light is not available.
