Perovskite solar cells carry the banner for emerging photovoltaics since they have demonstrated power conversion efficiency values well above 20%, which were traditionally only accessible for fairly established technologies such as silicon. Indeed, ABX₃ perovskite materials have revolutionized solar cells due to their ease of processing and outstanding electronic and optical properties, which make them ideal candidates for the development of multi-junction devices aiming to surpass limits associated to stand-alone technologies. In this review we discuss the latest regarding this matter. First, we introduce standard materials and processing techniques involved in the preparation of state-of-the-art perovskite solar cells. We then discuss the development of perovskite-based tandem devices in which ABX₃ perovskite acts as the active material in the top subcell and Si, CIGS, polymer, or ABX₃ act as bottom subcells. Finally, we provide the reader with a discussion on the different lines of research that this rapidly developing field may follow.

钙钛矿太阳能电池已经成为新兴光伏的旗帜，因为它们已经证明了功率转换效率值远高于20％，而传统上只有那些相当成熟的技术（如硅）才能使用。实际上，ABX ₃钙钛矿材料因其易于加工以及出色的电子和光学性能而彻底改变了太阳能电池，这使其成为开发多结器件的理想候选者，旨在突破与独立技术相关的限制。在这篇评论中，我们讨论有关此问题的最新消息。首先，我们介绍了制备最先进的钙钛矿太阳能电池所涉及的标准材料和加工技术。然后，我们讨论基于钙钛矿的串联设备的开发，其中ABX₃钙钛矿充当顶部子电池中的活性材料，Si，CIGS，聚合物或ABX ₃充当底部子电池。最后，我们为读者提供了关于这个快速发展的领域可能遵循的不同研究领域的讨论。
