Automated formulation and analysis of perovskite composition
Atinary Technologies aims to deploy its Self-driving Lab platform -SDLabs- to accelerate the formulation, analysis and stability testing of perovskite composition. Atinary will provide the software backbone to integrate various robotics, database, data analytics and proprietary ML algorithms into a closed-loop experimentation system. The overall experiment follows a three-step process -Design, Make and Test- orchestrated and driven by Atinarys SDLabs in the cloud. This allows remote control of the experiments, from anywhere on any devices.
