Technical FAQs 4

What is a photogenic cell based on?

A: A photogenic cell, or photocell, is a mechanical device used for converting light energy to electric energy. It is based on the photoelectric effect, which means that light causes electrons to be emitted from a material. Q: How does a photoelectric cell generate electricity?

Which material is used in a photovoltaic cell?

Fig. 1. Schematic diagram of a photovoltaic cell. Silicon is the most frequent material utilized in the manufacturing of solar cells. It has a bandgap of approximately 1.1 eV, meaning it can absorb photons with energy equal to or greater than this threshold.

What are the different types of photovoltaic cells?

Types of photovoltaic cells The development of PV cells has led to the creation of various types to address specific needs and challenges in solar energy generation. These include amorphous silicon, cadmium telluride, concentrated cells, dye-sensitized cells, and hybrid cells.

How do photovoltaic cells work?

Used in solar panels, photovoltaic cells work with the photovoltaic effect of converting solar energy to electrical energy. Photovoltaic cells use semiconductors, mostly silicon, which generates current with electric light exposure. Conversely, photoemissive cells work with the photoelectric effect.
