Advancements in Wearable Solar Cell Technology: Integrating Perovskites and Dye-Sensitized Cells for Future Electronics

The surge in wearable technology demands a sustainable power source to meet its impending growth. With billions of connected devices and escalating CO ₂ emissions, integrating solar energy into wearables emerges as a critical solution. While conventional solar cells have made strides, adapting them to wearable tech remains a challenge due to their limited flexibility. Silicon-based cells, the most efficient currently, face hurdles in achieving both flexibility and durability. Emerging solar cell types like Organic Photovoltaics (OPVs), perovskite-based, dye-sensitized, and quantum dot cells show promise for wearables, but each comes with integration complexities and material selection intricacies. This paper delves into the intricacies of solar cell integration into wearable tech, specifically focusing on perovskites and dye-sensitized solar cells due to their compatibility with current wearable technology. Exploring their design, operational mechanisms, and material adaptations, the paper highlights advancements, challenges, and the need for a delicate balance between mechanical flexibility and industrial feasibility in creating market-ready wearable solar technology.
