Question

If a photon of light has twice the energy required to excite an electron from valence to conduction band of material, what will happen with the energy when this photon strikes the solar photovoltaic cell? a. Two electrons will be generated for each photon. b. One electron will be generated and the energy above the band-gap of material will pass through the cell without any further effect. c. Energy in the excess of that required to excite the electron to conduction band will provide kinetic energy to electron and subsequently dissipate as heat. d. Additional 6.023 times 10^-23 holes will be created, resulting in doubling the current. e. No current will be generated, as the photon will pass through the cell without interaction.

Explanation / Answer

Correct option is c.

Excess energy will provide kinetic energy and liberated as heat.
