已经提出了中间带（IB）太阳能电池以增加太阳能电池的电流，同时保持输出电压，以便产生理想地高于由Shockley和Queisser在1961年建立的极限的效率。描述了概念，并解释了目前的实现和获得的理解。量子点被用来制造电池，但迄今为止所达到的效率还不令人满意。描述了克服所涉及问题的可能方法。或者，与早期的预测相反，已经制备了IB合金，并且已经制造了毫无疑问显示18行为的电池，尽管它们的效率仍然很低。这一概念的全面开发并非易事，但预计一旦完全掌握IB太阳能电池的开发，IB太阳能电池应该能够在聚光器中以非常高的效率串联运行，或者作为薄电池以低成本运行，效率高于目前的水平。
The intermediate band (IB) solar cell has been proposed to increase the current of solar cells while at the same time preserving the output voltage in order to produce an efficiency that ideally is above the limit established by Shockley and Queisser in 1961. The concept is described and the present realizations and acquired understanding are explained. Quantum dots are used to make the cells but the efficiencies that have been achieved so far are not yet satisfactory. Possible ways to overcome the issues involved are depicted. Alternatively, and against early predictions, IB alloys have been prepared and cells that undoubtedly display the 18 behavior have been fabricated, although their efficiency is still low. Full development of this concept is not trivial but it is expected that once the development of IB solar cells is fully mastered, IB solar cells should be able to operate in tandem in concentrators with very high efficiencies or as thin cells at low cost with efficiencies above the present ones.
