Mesoscopic perovskite solar cells (MPSCs) have captured intensive attention in the field of energy conversion due to the advantages of low material cost, simple fabrication process and high power conversion efficiency. Benefiting from the optimization of perovskite absorber deposition approaches, the design of new material systems, and the diversity of device concepts,the efficiency of MPSCs have increased from 2.19% in 2006 to a certified 21% in 2016. Such extremely fast increasing efficiency enables this photovoltaic technology challenge the current commercial solar cells. To meet the requirements of long-term stability for practical applications, we have been focusing on the strategies that can attain high stability for MPSCs, such as developing stable perovskite absorbers, enhancing the device stability through interface engineering and constructing hole-conductor-free devices. The hole-conductor-free printable MPSCs based on triple-layer of TiO2/ZrO2/Carbon have achieved remarkable device stability under heat stress, illumination and outdoor conditions. With an efficiency of over 15% and lifetime longer than 1000 h, this design offers a promising prospect for further applications.
