Long-term Environmental Benefits of Perovskite-on-Silicon Tandem Modules
Perovskite-on-silicon tandem solar modules offer several long-term environmental benefits compared to traditional silicon modules. Here are some key advantages:
- Reduced Overall Environmental Impact: When considering the additional energy generated over a 25-year lifetime, perovskite-on-silicon modules exhibit a 6% to 18% lower environmental impact than silicon modules alone. This is largely due to their higher efficiency, which can generate the same amount of electricity as a silicon heterojunction module in a shorter timeframe, specifically 22 years compared to 25 for silicon.
- Higher Efficiency: Tandem modules have higher power conversion efficiencies than silicon modules, which helps offset the increased environmental impacts from the additional materials and processes used in their production. Recent advancements have pushed efficiency past the 30% mark.
- Energy and Resource Efficiency: The production of silicon wafers represents a significant portion of the environmental impact associated with solar modules. While perovskite-on-silicon modules have additional impacts due to the perovskite material, their overall efficiency helps mitigate these effects by requiring less silicon over a given lifespan.
- Potential for Recycling and Circular Economy: Research into recycling perovskite and silicon from tandem modules can further reduce environmental impacts by capturing valuable materials and minimizing waste.
- Long-term Sustainability: As technology improves, the benefits of perovskite-on-silicon modules are likely to increase. This can lead to more sustainable energy production, especially if manufacturing processes become more environmentally friendly over time.
