Theoretically, introducing an IB allows two photons with energy fewer than the bandgap to excite an electron with the valence band for the conduction band. This increases the induced photocurrent and thereby effectiveness.[121] Gallium is often a by-product or service of significant temperature smelting of other metals, enabling GaAs cells https://zanedfedb.blogars.com/35348782/detailed-notes-on-longi-solar-panels
