The Potential of a Hybrid Energy System for Sustainable Development
Introduction
The researchers at Penn State University in the United States have developed a prototype of a hybrid energy system that combines solar cells for power production and radiative cooling for external cooling purposes. This innovative system aligns with the Sustainable Development Goals (SDGs) by promoting renewable energy and energy efficiency.
Key Findings
- The hybrid system has a cooling power of 63.8 W/m2 and a photovoltaic power output of 159.9 W/m2.
- The cooling capacity provided by the system can be used in buildings or refrigerators, contributing to SDG 7: Affordable and Clean Energy.
- The system achieves simultaneous subambient daytime radiative cooling and photovoltaic electricity generation from the same area, promoting SDG 13: Climate Action.
- The researchers demonstrated a temperature reduction of 5.1°C under solar irradiance of about 1,000 W/m2, showcasing the potential for energy savings and efficiency (SDG 12: Responsible Consumption and Production).
- The hybrid system’s cooling power is five times greater than conventional solar-reflective radiative coolers, highlighting its potential impact on energy conservation (SDG 7: Affordable and Clean Energy).
Methodology and Results
The system consists of a transparent low-iron glass radiative cooler, a visibly transparent infrared-opaque layer, and a 125 mm × 125 mm interdigitated back-contact (IBC) photovoltaic cell. The researchers tested the system in an outdoor environment and achieved significant cooling power and electricity generation.
Conclusion
This hybrid energy system demonstrates the potential of harnessing both solar energy and radiative cooling for renewable energy production and efficient cooling. By integrating these technologies, the system contributes to multiple SDGs, including SDG 7: Affordable and Clean Energy, SDG 12: Responsible Consumption and Production, and SDG 13: Climate Action. Further research and development in this field can lead to sustainable solutions for energy generation and conservation.
