Its photodetectors combine graphene transistors with a light absorbing layer.
Summary: TEHRAN (FNA)- Hybrid organic-inorganic perovskites have been used in optoelectronic devices including solar cells, photodetectors, light-emitting diodes and lasers, but the surface of hybrid perovskites is prone to surface defects, where charge carriers are trapped in the semiconducting material.
The photodetectors in these cameras remain susceptible to thermal noise, however, and since the equipment required for cooling them is quite large, it became necessary to find a way to reduce the cameras to a practical size.
