Revolutionizing Indoor Sensor Power: Rapid Microwave Annealing for ultra-low-cost Perovskite Solar Cells

Sensors, integral to modern life, are traditionally powered by batteries that generate toxic waste upon disposal. This project facilitates a sustainable alternative using photovoltaic (PV) cells, specifically perovskite PV cells, optimized for indoor lighting. Perovskite cells offer continuous power, ideal for low-power sensors. While cost-effective and suitable for roll-toroll fabrication, their widespread adoption is slowed down by the lengthy annealing time required. Our breakthrough significantly speeds up this process by 300% using microwave annealing. This rapid method not only accelerates production but also enhances cell quality. Our goal is to demonstrate the feasibility of this technique in roll-to-roll manufacturing, paving the way for large-scale, eco-friendly indoor sensor deployment. This innovation eliminates reliance on disposable batteries, aligning with environmental sustainability goals and advancing sensor technology for various applications.
