Photovoltaic cell data sheet

What is a photovoltaic cell?

Photovoltaic cell – The basic device that converts light into dc electricity; the building block of photovoltaic modules. a negative-type dopant. An electric field is established at the p-n junction which gives direction to the flow of light-stimulated electrons.

How much does a 20W photovoltaic system weigh?

The unframed types have a low profile approximately 9mm and are lightweight, the 20W version weighs only 1.49kg. A photovoltaic (PV) system may have a minimum of two components, the module and the load to be powered. An example of such a system would be a simple ventilation fan driven directly by a module during hot and sunny weather.

What is a thin film photovoltaic cell?

Thin-film cells – Photovoltaic cells made from a number of layers of photo-sensitive materials. These layers are typically applied using a chemical vapour deposition process in the presence of an electric field. Voltage regulator – A device that controls the operating voltage of a photovoltaic array.

What is the photovoltaic effect?

The photovoltaic effect is the conversion of sunlight into electricity. This occurs when the PV cell is struck by photons (sunlight), ‘freeing’ silicon electrons to travel from the PV cell, through electronic circuitry, to a load (Figure 1). Then they return to the PV cell, where the silicon recaptures the electron and the process is repeated.

How thick are photovoltaic cells?

Thick cells – Conventional cells, such as crystalline silicon cells, which are typically from 4 to 17mm thick. In contrast, thin-film cells are several microns thick. Thin-film cells – Photovoltaic cells made from a number of layers of photo-sensitive materials.
