In the past few years, a large variety of perovskite solar cells (PSCs) with vivid and well-distinguished color hues have been demonstrated. In this Perspective, we compare different strategies employed to realize colorful PSCs both in opaque and semitransparent designs. The approaches used to modulate the PSCs' colorful appearance can be divided into two main categories: the first one based on the modifications of their internal layers (, absorber, electron- and/or hole-transporting layers, and electrodes), while the second is based on the addition of external colored or nanostructured films to the standard PSCs. The advantages and bottlenecks of each strategy are discussed in terms of PSCs' color tunability, transparency, photovoltaic performances, fabrication processes feasibility, and scalability, in view of suitable applications in an urban context for building-integrated photovoltaics.
在过去几年中，已经展示出了各种各样具有鲜明且易于区分颜色色调的钙钛矿太阳能电池（PSC）。在这篇观点文章中，我们比较了用于实现不透明和半透明设计的彩色PSC所采用的不同策略。用于调节PSC彩色外观的方法可分为两大类：第一类基于对其内部层（即吸收层、电子和/或空穴传输层以及电极）的改性，而第二类则基于向标准PSC添加外部有色或纳米结构薄膜。鉴于在城市环境中适用于建筑一体化光伏的应用，从PSC的颜色可调性、透明度、光伏性能、制造工艺可行性和可扩展性等方面讨论了每种策略的优点和瓶颈。
