Achieving the spontaneous evolution of fuel from integrated devices by solar-driven water splitting is an attractive method for renewable energy conversion. However, their widespread implementation is hindered by their immature architectures and inferior performances. Here, we propose a real integrated device consisting of two series-connected perovskite solar cells (PSCs) and two CoP catalyst electrodes, which can be immersed into the aqueous solution directly for solar-driven water splitting. Benefiting from the low-cost and facile encapsulation technique, this integrated device possesses a compact structure and well-connected circuits for the process of charge carriers generation, transfer, and storage. Moreover, although all expensive components in this integrated device are eliminated, the two series-connected carbon-based PSCs still exhibit a high solar-to-electric efficiency of 10.6% as well as the integrated devices display a solar-to-hydrogen efficiency of as high as 6.7%. This integrated device serves as a model architecture toward future development and optimization of the integrated device that can be immersed into the aqueous solution directly for water splitting.

一种低成本，高效率的集成设备，用于太阳能驱动的水分解。
通过太阳能驱动的水分解来实现集成设备自发产生燃料是可再生能源转换的一种有吸引力的方法。但是，它们的广泛实施受到其不成熟的体系结构和性能不佳的阻碍。在这里，我们提出了一种真正的集成设备，该设备由两个串联的钙钛矿太阳能电池（PSC）和两个CoP催化剂电极组成，可以将其直接浸入水溶液中以进行太阳能驱动的水分解。受益于低成本和便捷的封装技术，该集成设备拥有紧凑的结构和连接良好的电路，可用于电荷载流子的生成，传输和存储。而且，尽管消除了该集成设备中所有昂贵的组件，这两个串联的基于碳的PSC仍显示出10.6％的高太阳能电效率，而集成器件显示出高达6.7％的太阳能电效率。该集成设备可作为模型开发的模型架构，可用于集成设备的未来开发和优化，该集成设备可直接浸入水溶液中进行水分解。
