“…The same colloid film is also used as the top layer ETL. Prior to the top layer, an underlayer SnO 2 ETL is formed by depositing SnO 2 sol–gel through CBD under specific conditions such as pH value, temperature, reaction time, solvent, and SnCl 2 precursor concentration, which are critical for achieving a highly uniform and thin film coverage. ,– The appropriate size distribution of SnO 2 sol–gel is observed by using dynamic light scattering (DLS) at an optimized SnCl 2 concentration of 150 mM (sol–gel@150 mM) presented in Figure a. Concentrations over 160 mM (sol–gel@160 mM) result in agglomeration or murky sol–gel as elucidated in Supporting Information, Figure S1a (right).…”

A tailored SnO 2 layer using double electron transport layers (ETLs) was designed to overcome interfacial energy barriers, enhance charge transport, and decrease charge recombination at the perovskite/ETL interfaces. Through this dual interfacial engineering approach, compact SnO 2 layers with an ideal interfacial energy-level alignment were prepared using SnCl 2 and NH 4 Cl salts, leading to efficient charge extraction. Stable perovskite solar cells with a power conversion efficiency of 21.46%, a high open-circuit voltage of 1.10 V, and a fill factor of 0.79 were successfully achieved using this approach. The devices also exhibited negligible hysteresis and no significant efficiency loss after a 2400 h stability test at ambient conditions without encapsulation. These results demonstrate an efficient approach to achieving high-quality ETL layers for efficient and stable solar cells.

Organometallic mixed halide perovskite solar cells (PSCs) have emerged as a promising photovoltaic technology with increasingly improved device efficiency exceeding 24%. Charge transport layers, especially electron transport layers (ETLs), are verified to play a vital role in device performance and stability. Recently, metal oxides (MOs) have been widely studied as ETLs for high‐performance PSCs due to their excellent electronic properties, superb versatility, and great stability. This Review briefly discusses the development of PSCs' architecture and outlines the requirements for MO ETLs. Additionally, recent progress of MO ETLs from preparation to optimization for efficient PSCs is systematically summarized and highlighted to associate the versatility of MO ETLs with the performance of devices. Finally, a summary and prospectives for the future development of MO ETLs toward practical application of high‐performance PSCs are drawn.

Summary Herein, the influence of Mg‐doped CdS nanocrystals (NCs) on the performance of hybrid solar cells (HSCs) is investigated for the first time. Pristine and Mg‐doped CdS NCs at different concentrations (0.25, 0.5, and 0.75 mol%) are synthesized using the heating up method. The effect of Mg on structural, compositional, morphological, optical, and electrical properties of CdS NCs is examined. The structural analysis showed a peak shift toward a higher wavelength, while lattice parameters a and c are decreased. As the Mg concentration increases, the shape and size of the CdS NCs are considerably changed, while the bandgap is tuned from 2.66 to 2.44 eV. Besides, the resistivity of CdS is significantly decreased while carrier concentration increases. Then, the device is fabricated with a configuration of FTO/TiO2/P3HT:PC61BM/MoO3/Ag, wherein the influence of different concentrations of undoped and Mg‐doped CdS NCs on the performance of HSCs is explored. The Mg‐doped CdS NCs exhibited a power conversion efficiency of 2.92%, 2.5 times higher than the polymer device. Thus, the results revealed that the Mg doping significantly improved the properties of CdS NCs and the performance of HSCs. Henceforth, this work would provide a new path to enhance the power conversion efficiency of the HSCs in a low‐cost approach.
