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 IB 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.
中间能带（IB）太阳能电池被提出用于增加太阳能电池的电流，同时保持输出电压，以产生理想效率超过 Shockley 和 Queisser 在 1961 年设定的效率限制。描述了该概念，并解释了目前的实现和已获得的理解。量子点用于制造电池，但迄今为止实现的效率还不尽如人意。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，并且已经制造了无疑显示 IB 行为的电池，尽管它们的效率仍然很低。这个概念的完全开发并不简单，但预计一旦完全掌握了 IB 太阳能电池的开发，IB 太阳能电池应该能够在具有非常高效率的聚光器中串联运行，或者作为低成本的薄电池运行，效率高于目前的电池。
