Introduction to Solar Cells
Solar cells are the electrical devices that directly convert solar energy (sunlight) into electric energy. This conversion is based on the principle of photovoltaic effect in which DC voltage is generated due to flow of electric current between two layers of semiconducting materials (having opposite conductivities) upon exposure to the sunlight [].

applications [13]. The solar energy data provides information on how much is the sun potential at a location on the earth''s during a specific time period [14, 15]. These data are very important for designing and sizing solar energy systems [16]. Due to the high cost and installation difficulties in solar measurement, the solar energy data are
How Does Solar Cell Output Vary with Incident Light Intensity?
Introduction. Solar cells are electronic devices that can transform light energy into an electric current.Solar cells are semiconductor devices, meaning that they have properties that are intermediate between a conductor and an insulator. When light of the right wavelength shines on the semiconductor material of a solar cell, the light creates a flow of electrons.
