碳基钙钛矿太阳能电池已经通过丝网印刷三个连续的二氧化钛、氧化锆和碳的中孔层而没有空穴传输层，并通过钙钛矿液体前体渗透通过这些层来构建。通过改变三层的厚度和用于丝网印刷的油墨的组成来优化电池效率。采用电化学阻抗谱作为指导，在搜索层厚度优化。所有电池构造和测试在20-30%湿度的环境条件下进行。细胞未被包封。最好的电池效率为10.7%。所有电池都表现出显著的稳定性，这是由低环境湿度和碳顶部组分的疏水性（因此具有保护性）支持的。
Carbon based perovskite solar cells have been constructed by screen-printing three subsequent mesoporous layers of Titania, Zirconia and Carbon without a hole transporting layer and by infiltration of perovskite liquid precursor through the layers. Cell efficiency was optimized by varying the thickness of the three layers and the composition of the inks employed for screen printing. Electrochemical impedance spectroscopy was employed as a guide in the search for layer thickness optimization. All cell construction and testing was carried out under ambient conditions of 20–30% humidity. The cells were not encapsulated. The best cell gave an efficiency of 10.7%. All cells demonstrated a remarkable stability supported by the low ambient humidity and the hydrophobic, therefore protective, nature of the carbon top component.
