At present, the most frequent example of the above-described solar cell structure is realized with crystalline silicon (c-Si). A typical c-Si solar cell structure is shown in Figure 3.1. A moderately-doped p-type c-Si with an acceptor concentration of 1016 cm-3 is used as an absorber.
SEV can achieve low-carbon, energy saving, environmental protection and true zero-emissions for the future of human life. A solar cell is an electronic device which can use photovoltaic (PV) effect to directly convert sunlight into electricity. Light shining the solar cell will produce both a voltage and a current to generate electric power .
A solar module consists of number of interconnected solar cells. These interconnected cells embedded between two glass plate to protect from the bad whether. Since absorption area of module is high, more energy can be produced. Solar energy is clean and non-polluting.
Solar PV cells consist of two types of semiconductor solar elements – p-type and n-type silicon. The difference lies in the type of charge carriers. An electric field forms between the two semiconductor layers. When a photon of sunlight knocks a free electron loose, the electric field pushes it out of the silicon junction.
A typical c-Si solar cell structure is shown in Figure 3.1. A moderately-doped p-type c-Si with an acceptor concentration of 1016 cm-3 is used as an absorber. On the top side of the absorber a thin, less than 1 μm thick, highly-doped n-type layer is formed as the electron membrane.
The frame serves to protect the internal components of the battery and provides a sturdy structure for installing the solar PV cells panel. Popular frames are made of aluminum, with the IMARC Group forecasting a market growth rate of 10.6% by 2028.
