This research aims to design and analyze an Internet of Things (IoT)-based monitoring system to observe the performance of Organic Solar Cells (OSC) sensitized with variations of chlorophyll dye and mixed dyes (anthocyanin + chlorophyll + carotene). The system uses an INA219 sensor to measure voltage and current, which are then transmitted in real-time via the ESP32 WiFi module to the Blynk app…
