Abstract

Low-power IoT sensing applications have proliferated, focusing on self-powered sensors. Accordingly, researchers have investigated serval procedures for the power management of such self-powered sensors. Obesely, minimizing the energy consumed by the sensor is critical to efficient power management. However, another challenge is still considered in harvesting energy effectively. Herein, we provide an attempt to investigate light harvesters that are capable of semi-transparent applications. Six samples were simulated under three light sources while performing a unifacial and bifacial optical injection. The optoelectronic numerical model has shown the utility of perovskite solar cells to harvest the AM1.5G solar spectrum up to 28.63%, with transparency reaching 87%. On the other hand, the bifacial condition boosted the overall cell efficiency to nearly 33% with transparency of 90%, without considering Fresnel glass reflection of 8%. The proposed bifacial cell is a primary light-harvesting source for four IoT sensing applications, including biomedical sensing, underwater harvesting, and IoT sensing in intelligent vehicles and buildings.
