In Chap. 5, we derived the single-junction solar cell conversion efficiency within the framework of the detailed balance theory and computed the solar spectrum by employing Planck''s law for black-body radiation.As explained in Sect. 2.2, the solar spectrum that passes the atmosphere differs according to the amount of air passed.
Light Generated Current
The generation of current in a solar cell, known as the "light-generated current", involves two key processes. The first process is the absorption of incident photons to create electron-hole pairs. Electron-hole pairs will be generated in the solar cell provided that the ...
