Solar cell efficiency is the ratio of the electrical output of a solar cell to the incident energy in the form of sunlight. The energy conversion efficiency (η) of a solar cell is the percentage of the solar energy to which the cell is exposed that is converted into electrical energy. This is
Working Principle of Photovoltaic Cells. A photovoltaic cell essentially consists of a large planar p–n junction, i.e., a region of contact between layers of n- and p-doped semiconductor material, where both layers are electrically contacted (see below). The junction extends over the entire active area of the device.
