We’re excited to share our latest publication in the Chemical Engineering Journal (Vol. 510, April 2025), titled:
“Efficient self-charging monolithic photocapacitors comprised of perovskite solar cell and quasi-solid-state supercapacitor through a shared Janus carbon electrode”
As global demand for sustainable energy rises, so does the need for integrated systems that can harvest, convert, and store solar energy seamlessly. In this study, we developed high-performance self-charging monolithic perovskite-based photocapacitors (MPPCs)—devices that combine a perovskite solar cell and a quasi-solid-state supercapacitor through a shared biomass-derived Janus carbon electrode.
🔋 Key highlights from the study:
- Record-breaking overall efficiencies:
▪️ 7.29% (active area: 0.115 cm²)
▪️ 4.71% (active area: 1.0 cm²) - Excellent operational durability:
▪️ 77.14% efficiency retention
▪️ 98.90% capacitance retention after 50 continuous cycles - Demonstrated real-world potential by powering devices like digital hygrometers, buzzers, and LEDs via a three-cell MPPC power pack.
This work positions carbon-based MPPCs as a scalable, low-cost, and sustainable solution for powering low-power electronics — especially in off-grid and wearable applications.
