What is a band gap in a solar cell?

The band gap represents the minimum energy required to excite an electron in a semiconductor to a higher energy state. Only photons with energy greater than or equal to a material's band gap can be absorbed. A solar cell delivers power, the product of current and voltage.

How do you determine a material's promise in photovoltaics?

If one were to choose a single parameter to perform a first screen to determine a material’s promise in photovoltaics, it would be its band gap. The band gap represents the minimum energy required to excite an electron in a semiconductor to a higher energy state.

Do thermalization and sub-band gap transmission limit the efficiency of a solar cell?

Thermalization and sub-band gap transmission limit the efficiency of a solar cell. 1 Tandems expand the spectral absorption range compared to a single-junction solar cell by integrating materials with a lower band gap.
