研究目的
Investigating the efficiency and spectral performance of narrowband organic and perovskite photodetectors for applications in wearable electronics, the Internet of Things, computer vision, artificial vision, and biosensing.
研究成果
Organic and perovskite narrowband photodetectors have shown significant progress, with organic photodetectors being more mature for technological deployment due to higher photoconversion efficiencies and better spectral widths. Perovskite photodetectors, while promising, face challenges in achieving similar performance levels and mechanical flexibility.
