3.2.1 Absorption and Energy Conversion of a Photon. When light illuminates a solar cell, the semiconductor material absorbs photons; thereby, pairs of free electrons and holes are created (see Fig. 3.1).However, in order to be absorbed, the photon must have an energy E ph = hν (where h is Planck''s constant and ν the frequency of light) higher or at least equal to …
For silicon solar cells, a more realistic efficiency under one sun operation is about 29% 2. The maximum efficiency measured for a silicon solar cell is currently 26.7% under AM1.5G. The difference between the high theoretical efficiencies and the efficiencies measured from terrestrial solar cells is due mainly to two factors.
