“…The better PCE was 22.06%, based on a SnO 2 @Na:Cs ETL. Gu et al [88] added NaCl to raise the charge exchange between the SnO 2 ETL and perovskite and obtained a PCE of 21.2%. Large-scale fabrication methods include vacuum thermal evaporation [89], magnetron sputtering [90], radio frequency [91,92], sputtering deposition [93], spray deposition [94,95], atomic layer deposition [96], hydrothermal [97], and printing [98].…”

The power conversion efficiency (PCE) of perovskite solar cells (PSCs) has seen effective performance upgrades, showing remarkable academic research and commercial application value. Compared with commercial silicon cells, the PCE gap is narrowing. However, the stability, cost, and large-scale production are still far behind. For scale-up preparing high-efficiency and stable PSCs, there is a variety of related research from each functional layer of perovskite solar cells. This review systematically summarizes the recent research on the functional layers, including the electron transport layer, perovskite layer, hole transport layer, and electrode. The common ETL materials, such as TiO2, SnO2, and ZnO, need doping and a bi-layer ETL to promote their property. Large-scale and low-cost production of perovskite layers with excellent performance and stability has always been the focus. The expensive and instability problems of Spiro-OMeTAD and electrode materials remain to be solved. The main problems and future development direction of them are also discussed.

“…[3,4] The short-time rapid increase in power conversion efficiencies (PCEs) of perovskite solar cells (PSCs) from 3.5% to 26% indicates the upcoming replacement of conventional solar cell devices with PSCs. [5] PSCs are now at the forefront of the race to develop the next generation of low-cost PV and integrated technologies due to this huge improvement in PV performance. Additionally, PSCs have the edge over conventional Si solar cell technology, which has high manufacturing costs and complicated manufacturing routes.…”

In this work, the efficiency of lead‐free La2NiMnO6 (LNMO)‐based double perovskite solar cells is optimized using solar cell capacitance simulator (SCAPS‐1D). Herein, the device performance is boosted by using different combinations of electron‐transport layers, hole‐transport layers, absorber layer thickness, acceptor doping density, acceptor defect density, and bandgap tuning, and by modifying the electron affinity. To make the device more realistic, the performance of the proposed device is carefully modified in the presence of interface defect density ≈10−13 cm−3, series resistance ≈1 Ω cm2, and shunt resistance ≈6000 Ω cm2, respectively. From the findings, the optimized device exhibits a record open‐circuit voltage = 1.23 V, short‐circuit current density = 27.18 mA cm−2, fill factor = 87.14%, and power conversion efficiency = 29.20% for FTO/SnO2/LNMO/MoO3/Au configuration. Finally, the device performance is tested under different working temperatures, and 300 K is found as the best temperature for the device.
