While perovskite-based photovoltaic systems demonstrate superior techno-economic and environmental advantages over silicon-based systems, achieving maximum circularity does not automatically equate to the most sustainable outcome. This sustainability research insight is drawn from a 2023 study published in Journal of Industrial Ecology. Using Process simulation, life cycle assessment (lca), techno-economic assessment (tea), circularity assessment, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing photovoltaic systems, prioritize emerging technologies like perovskites for their superior environmental and economic profiles, but critically evaluate circularity strategies to ensure they lead to genuinely optimized sustainability rather than just maximizing material loops.

Application

Design takeaway

When designing photovoltaic systems, prioritize emerging technologies like perovskites for their superior environmental and economic profiles, but critically evaluate circularity strategies to ensure they lead to genuinely optimized sustainability rather than just maximizing material loops.

How to apply

When evaluating new product designs, especially in energy technologies, conduct a combined life cycle, techno-economic, and circularity assessment to identify the most sustainable and cost-effective solutions. Consider how policy changes might interact with your design choices.

Project actions

  • 01When researching materials for a design project, look beyond just their primary function to consider their entire life cycle impact.
  • 02Explore how different end-of-life scenarios (e.g., recycling, reuse, remanufacturing) affect the overall sustainability of your design.

Method & Evidence

AimTo assess the combined environmental and techno-economic performance of silicon- and perovskite-based photovoltaic life cycles, predicting the effects of circularity on resource efficiency, carbon footprint, and electricity cost.
MethodProcess simulation, Life Cycle Assessment (LCA), Techno-economic assessment (TEA), Circularity assessment
ProcedureThe study used process simulation to resolve mass and energy balances for three photovoltaic life cycles. It then simultaneously assessed environmental and techno-economic performance, predicting the effects of circularity on resource efficiency, carbon footprint, and levelized cost of electricity. Material and energy resource models were linked with techno-economic models to explore the impacts of carbon taxation and the moderating effects of circularity.

Strengths & Limitations

Strengths

  • +Combines multiple assessment methods (LCA, TEA, circularity).
  • +Provides a prospective analysis of emerging technologies.
  • +Investigates the interplay between circularity and policy impacts.

Limitations

It's difficult to get perfect data for the entire life cycle of a product. The study relies on predictions and simulations, which might not be exactly how things turn out in the real world.

Reliability & validity

The study's validity is supported by its use of established assessment frameworks (LCA, TEA) and process simulation. Reliability is enhanced by generating a single inventory dataset per life cycle to ensure alignment across different assessments.

Think critically

If maximum circularity doesn't always mean maximum sustainability, what other factors should designers prioritize when aiming for a truly sustainable product?

05

Design Principles

"Holistic sustainability assessment is crucial, integrating techno-economic factors, environmental impacts, and circularity principles to avoid sub-optimal outcomes."

This research highlights the critical need for a holistic approach to photovoltaic system design and deployment. Designers and engineers must consider not only the inherent material and manufacturing advantages of emerging technologies like perovskites but also the nuanced relationship between circular economy principles and overall environmental impact.

06

What This Means for Your Design

Newer solar panels (perovskites) are better than old ones (silicon) for the planet and cost. Making them easier to recycle helps, but just recycling a lot isn't always the best way to be truly sustainable.
