Photoconductivity equation
WebThe paper reported a theoretical study on the photoconductivity of a bifacial silicon solar cell under polychromatic illumination and a constant magnetic field effect. By use of the continuity equation in the base of the solar cell maintained in a constant temperature at 300 K, an expression of the excess minority carriers’ density was determined according to the … WebJun 8, 2024 · In the Simmons–Taylor equation, at steady-state condition, generation rate (G) is equal to recombination rate (U); at that situation, free electron concentration n (G) and free hole concentration p (G) can be determined from the experimentally measured photoconductivity and expressed in Eq. 1.
