Abstract Organic semiconductors have attracted tremendous attention in the past few years, thanks to their excellent flexibility, solution‐processability, low‐cost, chemical versatility, etc. Particularly, organic solar cells based on ternary heterojunctions shown remarkable device performance, with recent development of nonfullerene acceptor materials. These novel materials are also promising for photodetection. However, there several key limits facing photodetectors, such as relatively...
Abstract Inverted planar perovskite solar cells (PSCs) exhibit advantages in terms of simple device fabrication, good reproducibility, and less hysteresis. However, there still remain challenges to passivate the trap states within film reduce interface instability arising from penetration moisture diffusion metal electrode. In this work, passivation is reported using gradiently distributed nonfullerene electron‐rich Lewis bases small molecule IDIC (a π‐conjugated base: indacenodithiophene...
Conventionally, wavelength‐selective ultraviolet photodetection is achieved by using broadband inorganic photodiodes coupled with optical filters, which significantly increases the complexity and fabricating cost of devices for high pixel density imaging systems. Here, a facile approach to achieve tunable spectral response without filters demonstrated. The are based on ZnO heterojunctions, spectra effectively modulated tuning position charge generation, results in distinct charge‐collection...
Ultraviolet (UV) photodetectors have attracted significant attention because of their wide applications in environment monitoring, flame detecting, missile tracking, and so on. However, commercial UV based on bandgap inorganic semiconductors normally require high‐vacuum high‐temperature deposition techniques. To reduce the fabrication cost, solution‐processed organic or hybrid are introduced as promising candidates for low‐cost detection. Particularly, due to low flexibility, chemical...
