High-Efficiency Multi-functional Integrated Flexible Perovskite Photovoltaic Cells and Silicon Photo
This invention is a flexible thin-film device that can generate electricity from sunlight and transmit data at the same time. It combines advanced perovskite solar cell materials with silicon photonic communication technology in a single integrated structure.
The film captures sunlight very efficiently using special light-trapping structures and nano-materials, converts it into electrical energy, and also uses part of the light for high-speed optical data transmission. Heat generated during operation is recycled and managed to improve stability and lifespan.
Because it is thin, lightweight, and flexible, the invention can be applied to many surfaces such as buildings, vehicles, sensors, and smart devices. It provides a new solution where power generation and communication are combined into one smart material, reducing system complexity and improving overall efficiency.
Today’s solar panels mainly focus on generating electricity, but they cannot transmit data. At the same time, communication systems require separate power supplies, wiring, and hardware, which increases cost, weight, and energy loss.
Perovskite solar cells are promising but often suffer from stability issues, heat buildup, and limited integration with other technologies. Silicon photonic systems are excellent for high-speed data transmission, but they are rarely combined with energy-harvesting materials.
This separation between power generation and communication creates inefficiencies, especially for smart surfaces, IoT devices, remote sensors, and autonomous systems where space, weight, and power are limited.
The invention solves these problems by integrating a high-efficiency perovskite photovoltaic layer with silicon photonic transmission modules in one flexible film.
Special nano-structures such as quantum dots, photonic crystals, and plasmonic particles improve light absorption and electrical performance. Silicon photonic waveguides and modulators embedded in the structure enable high-speed optical data transmission (10–100 Gbps).
Additional thermal management and thermoelectric layers recover heat and maintain stable operation. The result is a single multifunctional material that produces energy, communicates data, and manages heat simultaneously.
Current technologies treat energy generation and data communication as separate systems, leading to higher cost, lower efficiency, and complex installation. Existing perovskite solar cells also struggle with long-term stability and heat management.
This invention overcomes these defects by combining both functions in one integrated structure, improving efficiency, reducing material redundancy, and enabling new smart applications that were not practical before.
