Theoretically, introducing an IB enables two photons with energy lower than the bandgap to excite an electron from the valence band to the conduction band. This increases the induced photocurrent and therefore performance.[121] The 1st instance of photovoltaic cells in vehicular programs was close to halfway through the second 50 https://than-rak37148.blogoxo.com/36797208/what-are-solar-cells-can-be-fun-for-anyone
