In the past few years, a large variety of perovskite solar cells (PSCs) with vivid and well-distinguished color hues have been demonstrated. In this Perspective, we compare different strategies employed to realize colorful PSCs both in opaque and semitransparent designs.
Herein, inspired by the function of human visual cells, we develop a high-resolution perovskite-based color camera using a set of narrowband red, green, blue, and broadband white perovskite photodetectors as imaging sensors.
Moreover, perovskites can be a potential material for the electrolytes to improve the stability of batteries. Additionally, with an aim towards a sustainable future, lead-free perovskites have also emerged as an important material for battery applications as seen above.
In this work, we have demonstrated a perovskite-based color camera based on the RGBW perovskite PDs to mimic the SML cone cells and rod cells of the human eye, combined with a predesigned pattern illumination and image reconstruction technology.
Photo-charged battery devices are an attractive technology but suffer from low photo-electric storage conversion efficiency and poor cycling stability. Here, the authors demonstrate the use of perovskite solar cells in conjunction with a lithium ion battery which displays excellent properties.
In various dimensions, low-dimensional metal halide perovskites have demonstrated better performance in lithium-ion batteries due to enhanced intercalation between different layers.
