Perovskite solar panels have promising applications in powering Internet of Things (IoT) devices, especially under indoor conditions, due to their unique properties and performance advantages over traditional solar cells. Here are the key potential applications and benefits:
Powering IoT Devices with Indoor Energy Harvesting
- Efficient indoor photovoltaic (IPV) power source: Perovskite solar cells (PSCs) exhibit high efficiency under indoor light conditions, making them ideal for powering low-energy IoT devices that operate within buildings or other enclosed spaces. Studies have shown that a small PSC with an active area of about 1 cm² can generate enough energy to power typical low-power wireless IoT devices on most days of the year, assuming proper orientation and some energy storage for low-light days.
- Stable performance in realistic environments: PSCs have demonstrated good retention of performance over long periods (e.g., one year) when properly encapsulated, making them reliable for continuous IoT operation without frequent maintenance or battery replacements.
Advantages Over Conventional Power Sources
- Overcoming battery limitations: Conventional batteries are limited by weight, rigidity, lifespan, and use of toxic, scarce materials. Perovskite solar panels offer a lightweight, flexible, and environmentally friendly alternative that can reduce dependence on batteries and the need for frequent replacements.
- Cost-effective and sustainable: Advances in materials selection and printing techniques, as developed in projects like SPOT-IT, are improving the cost-effectiveness, stability, and sustainability of perovskite-based photovoltaic solutions suitable for IoT applications.
Enabling More Diverse and Wearable IoT Devices
- Integration in wearables and textiles: Perovskite solar technology’s ability to operate efficiently under low light and its flexibility allow integration into wearable devices and clothing. This can enable continuous power supply or recharging capabilities for small IoT devices such as smartwatches, fitness trackers, headphones, and even wirelessly charging smartphones carried in a jacket pocket.
- Expanding autonomous IoT devices: Perovskite solar panels can extend the range and functionality of IoT devices that are difficult to connect to the grid or replace batteries, such as distributed sensors and smart objects in smart cities, buildings, and industrial environments.
Sensor and Energy Module Applications in IoT Systems
- Beyond power generation—sensor integration: Metal halide perovskites also have applications in IoT sensor technologies, such as gas, humidity, photoelectric, and optical sensors, leveraging their excellent photoelectric properties and adjustable bandgap. This synergy can enable IoT devices that combine sensing and self-powering capabilities for enhanced functionality and endurance in multi-scenario applications.
