Bifacial Perovskite: Revolutionizing Renewable Energy

• Discover how innovative bifacial perovskite solar cells could revolutionize the renewable energy landscape, delivering higher efficiency at reduced costs with potential for 10-20% more power generation than monofacial modules. Research funded by the US DOE.

A study conducted by researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) has revealed the potential of bifacial perovskite solar cells to revolutionize the renewable energy landscape. Unlike monofacial cells, bifacial cells are able to capture direct sunlight on the front and harness reflected sunlight on the back, resulting in dual-sided energy yield and the potential of higher efficiency at reduced costs. NREL scientists, along with collaborators from the University of Toledo, devised an innovative cell design that achieved an efficiency exceeding 23% on the front side and 91% to 93% efficiency on the back side. They also determined that an ideal perovskite layer thickness is approximately 850 nanometers.
The findings of the study suggest that bifacial perovskite solar modules may ultimately generate 10% to 20% more power than monofacial modules, leading to better financial returns over time despite higher initial investment. The research was funded by the U.S. Department of Energy Solar Energy Technologies Office, demonstrating the government’s commitment to advancing solar energy technologies and sustainable power generation.

What Are the Benefits of Bifacial Perovskite Solar Cells?

As for now, the possible benefits of using bifacial perovskite solar cells are:

• Higher energy efficiency than traditional solar cells due to their ability to capture and convert multiple wavelengths of light.
  
• Improved stability under real-world conditions such as high temperatures and sunlight exposure due to its crystallization of organic molecules.
• Innovative upconversion devices for commercial solar cells due to its utilization of multiple photons.
• Significant reduction of engineering challenges for their viability.
• Ability to reduce the cost of solar energy production with improved efficiency and reduced engineering requirements.
