Low-temperature solution-processing method is a kind of low-energy-consuming and simple methodology for preparing cost-effective planar perovskite solar cells (PSCs). To achieve high-effciency planar PSCs, the quality of electron-transporting layers (ETLs) play a key role. The solvothermal-synthesized organic ligands capped semiconductor nanocrystals (NCs) not only have high crystallinity but also show excellent film-formation. Nevertheless, the biggest problem is that these organic ligands will form insulating barriers around the NCs, which will seriously hinder electronic coupling and limit performance of the corresponding devices. Therefore, the stripping treatment for organic ligands, which is not only complex but also has destructive influence on the quality of films, is traditionally used for achieving good performance. Here, we select high crystalline oleic acid-capped SnO2 NCs to prepare ETLs with low-temperature solution-processed methodology without complex ligand stripping step. We use Nb[Formula: see text] doping route to further enhance photovoltaic performance of the planar PSCs. The champion PSC based on Nb-doped SnO2 NCs ETL achieves a power conversion efficiency of 20.07%.

Abstract As a promising photovoltaic technology, perovskite solar cells (pero-SCs) have developed rapidly over the past few years and the highest power conversion efficiency is beyond 25%. Nowadays, the planar structure is universally popular in pero-SCs due to the simple processing technology and low-temperature preparation. Electron transport layer (ETL) is verified to play a vital role in the device performance of planar pero-SCs. Particularly, the metal oxide (MO) ETL with low-cost, superb versatility, and excellent optoelectronic properties has been widely studied. This review mainly focuses on recent developments in the use of low-temperature-processed MO ETLs for planar pero-SCs. The optical and electronic properties of widely used MO materials of TiO2, ZnO, and SnO2, as well as the optimizations of these MO ETLs are briefly introduced. The commonly used methods for depositing MO ETLs are also discussed. Then, the applications of different MO ETLs on pero-SCs are reviewed. Finally, the challenge and future research of MO-based ETLs toward practical application of efficient planar pero-SCs are proposed. Graphical abstract

The electron transport layer (ETL) is critical to carrier extraction for perovskite solar cells (PSCs). Moreover, the morphology and surface condition of the ETL could influence the topography of the perovskite layer. ZnO, TiO2, and SnO2 were widely investigated as ETL materials. However, TiO2 requires a sintering process under high temperature and ZnO has the trouble of chemical instability. SnO2 possesses the advantages of low-temperature fabrication and high conductivity, which is critical to the performance of PSCs prepared under low temperature. Here, we optimized the morphology and property of SnO2 by modulating the concentration of a SnO2 colloidal dispersion solution. When adjusting the concentration of SnO2 colloidal dispersion solution to 5 wt.% (in water), SnO2 film indicated better performance and the perovskite film has a large grain size and smooth surface. Based on high efficiency (16.82%), the device keeps a low hysteresis index (0.23).
