Question
The eco-friendly photodetector developed by ARCI and IIT
Hyderabad is based on which double perovskite material?Solution
The newly developed photodetector uses a lead-free double perovskite material, Cs ₂ AgBiBr ₆ . This material replaces toxic lead-based perovskites traditionally used in high-performance photodetectors. The innovation provides stable performance and supports self-powered operation under visible light, making it environmentally safer and suitable for sustainable electronics manufacturing.
