Band gap
The optical band gap (see below) determines what portion of the solar spectrum a photovoltaic cell absorbs. [12] Strictly, a semiconductor will not absorb photons of energy less than the band gap; whereas most of the photons with energies exceeding the band gap will generate heat. Neither of them contribute to the efficiency of a solar cell.
Band Gap
Overview. The band gap is the minimum amount of energy required for an electron to break free of its bound state. When the band gap energy is met, the electron is excited into a free state, and can therefore participate in conduction.

THE BEHAVIOUR OF SOLAR CELLS
A silicon solar cell is a diode formed by joining p-type (typically boron doped) and n-type (typically phosphorous doped) silicon. Light shining on such a cell can behave in a number of ways, as illustrated in Fig. 3.1. To maximise the power rating of a solar cell, it must be designed so as to maximise desired absorption (3) and absorption after
