The Working Principle of a Solar Cell
The two most important loss mechanisms in single bandgap solar cells are the inability to convert photons with energies below the bandgap to electricity and thermalisation of photon energies exceeding the bandgap, as illustrated in Fig. 3.1 (b). These two mechan-isms alone amount to the loss of about half the incident solar energy in the conversion
