High-performance large-area blade-coated perovskite solar cells with low ohmic loss for low lighting indoor applications

Perspectives for the conversion of perovskite indoor photovoltaics into IoT reality

“…7a) for the preparation of high-quality perovskite films with low ohmic loss. 95 With the modified perovskite film, the 1 cm 2 devices exhibited the PCE of 30.0% (100 lux) and 33.8% (1000 lux). Furthermore, the author successfully fabricated a self-powered drive LED indicator under indoor condition by connecting four sub-cells (each with an active area of 1 cm 2 ) in series.…”

Recent Strategies for High-Performing Indoor Perovskite Photovoltaics

“…The reduced defect density facilitated the higher performance of the C 60 ETL compared to that of the spin-coating method. Unfortunately, this method is not favorable for commercialization because of the high vacuum required during deposition; thus, other methods, such as roll-to-roll [ 116 ] or blade coating [ 57 ] are preferred. Blade-coated devices exhibited 33.8% PCE for 1 cm 2 devices under 1000 lx of white LED illumination and were further able to power up a LED by connecting some devices in series with a total active area of 4 cm 2 , as shown in Figure 5 c,d.…”

Blade-coating of a highly crystallized lead-free silver-bismuth halide double perovskite thin film with improved stability for high-performance photodetection

“…In this regard, the blade-coating method is suitable because of its high material utilization efficiency, in situ crystallization, and adjustable parameters. [27][28][29] In this study, high-quality (111)-oriented Cs 2 AgBiBr 6 double perovskite thin films with a large grain size (3 mm) and large area (B10 cm 2 ) were prepared via a one-step blade-coating method. Photoluminescence (PL) mapping and time-resolved photoluminescence (TRPL) measurements indicate that grain boundaries are the dominant non-radiative recombination sites.…”
