“…The surface modification of SnO 2 by other metal oxides ZnO and Sb 2 O 3 can also benefit electron extraction and suppress electron–hole recombination. [18b,92,98] It is well to be reminded that MgO is a good tunneling and spintronics material, which could modify the interface and retard electron–hole recombination . Our group incorporated an ultrathin dielectric MgO nanolayer between FTO electrode and SnO 2 ETL of PSCs, realizing enhanced electron transporting and hole blocking properties.…”

SnO 2 has been well investigated in many successful state-of-the-art perovskite solar cells (PSCs) due to its favorable attributes such as high mobility, wide bandgap, and deep conduction band and valence band. Several independent studies show the performances of PSCs with SnO 2 are higher than that with TiO 2 , especially in device stability. In 2015, the first planar PSCs were reported with a power conversion efficiency over 17% using a low temperature sol-derived SnO 2 nanocrystal electron transport layer (ETL). Since then, many other groups have also reported high performance PSCs based on SnO 2 ETLs. SnO 2 planar PSCs show currently the highest performance in planar configuration devices (21.6%) and are close to the record holder of TiO 2 mesoporous PSCs, suggesting their high potential as ETLs in PSCs. The main concerns with the application of SnO 2 as ETL are that it suffers from degradation in high temperature processes and that its much lower conduction band compared to perovskite may result in a voltage loss of PSCs. Here, notable achievements to date are outlined, the unique attributes of SnO 2 as ETLs in PSCs are described, and the challenges facing the successful development of PSCs and approaches to the problems are discussed.

Organic‐inorganic hybrid perovskite solar cells (PSCs) have developed rapidly in recent years owing to the low cost and high power conversion efficiency achieved. The excellent performance of PSCs is attributed to the superior electrical properties of each layer, including the electron transport layer (ETL), light‐harvest layer, hole transport layer. As one of the most promising ETL materials for PSCs, SnO2 shows excellent transmission, an appropriate energy band gap, a deep conduction band level, and high electron mobility, leading to efficient electron extraction and transport. Here, recent advancements in the PSCs with SnO2 ETLs and endeavors aimed at improving the performance of this photovoltaic device are reviewed. Several typical configurations of SnO2 based PSCs are discussed, including the planar structure, mesoporous structure, inverted structure and flexible PSCs. The efforts of modification and composite SnO2 with other metal oxides are also assessed. Finally, an overview of the perspectives and challenges for the future of SnO2 based PSCs is provided.

Halide perovskite solar cells based on CH 3 NH 3 PbI 3 and related materials have emerged as the most exciting development in the next generation photovoltaic technologies, yet the microscopic phenomena involving photo-carriers, ionic defects, spontaneous polarization, and molecular vibration and rotation interacting with numerous grains, grain boundaries, and interfaces are still inadequately understood. In fact, there is still need for an effective method to interrogate the local photovoltaic properties of halide perovskite solar cells that can be directly traced to their microstructures on one hand and linked to their device performance on the other hand. In this perspective, we propose that scanning probe microscopy (SPM) techniques have great potential to realize such promises at the nanoscale, and highlight some of the recent progresses and challenges along this line of investigation toward local probing of photocurrent, work function, ionic activities, polarization switching, and chemical degradation. We also emphasize the importance of multi-modality imaging, in-operando scanning, big data analysis, and multidisciplinary collaboration for further studies toward fully understanding of these complex systems.
