The extra electron fills up the lower-energy state in the conduction band, causing excited electrons to, effectively, spill over into the higher-energy, photon-emitting state.
这个额外的电子填充了传导带的较低能级，有效的导致了被激发的电子溢入较高，释放光子的能级。
The second strategy was to lower the energy difference between the two conduction-band states so that excited electrons would be more likely to spill over into the photon-emitting state.
第二步策略是减小两个传导带态的能量落差，这样一来受激发电子就更容易溢入光子释放态。
If the photon energy is greater than the bandgap of the cell material, then electrons are excited into the conduction band.
