Key Findings

01For solar PV, material selection and fabrication processes for electrode and absorber layers are critical for reducing life cycle environmental impacts.
02Optimized material combinations for perovskite solar cells can achieve a global warming potential as low as 0.12–0.15 kg CO2 eq/kWh and reduce mineral/metal resource use.
03For CSP, eco-design should focus on minimizing natural gas use in co-generation, and improving the environmental performance of collectors, heat transfer fluids, and power generation units.
04While transportation, consumption, and end-of-life stages have smaller individual impacts, they contribute to the overall effectiveness of eco-design measures when considered holistically.
05Implemented eco-design measures reduce both environmental impacts and electricity costs, accelerating market readiness.

Application

Design takeaway

How to apply

When designing new solar energy systems or components, conduct a preliminary LCA to identify the most impactful stages and materials. Prioritize research into alternative materials and manufacturing techniques that offer improved environmental and economic profiles.

Project actions

01When researching materials for your design, look for data on their environmental impact (e.g., carbon footprint, resource depletion).
02Consider the energy and waste generated during the manufacturing process of your chosen components.

DV["Global Warming Potential (kg CO2 eq/kWh)","Mineral and metal resource use (kg Sb eq)","Electricity cost ($/kWh)"]

CV["Type of solar technology (PV vs. CSP)","Scale of technology (lab-scale vs. commercial)","Specific manufacturing processes"]

Strengths & Limitations

Strengths

+Integrates both environmental and economic assessments (LCA and LCC).
+Provides specific recommendations for different types of solar technologies (PV and CSP).
+Highlights the importance of a holistic lifecycle perspective.

Limitations

Conducting a full LCA can be complex and data-intensive. For a design project, focus on identifying the most significant impact areas based on available information.

Reliability & validity

The reliability of LCA and LCC depends heavily on the quality and completeness of the data used. The validity of the findings is strengthened by applying both methodologies to specific technologies, but may be limited by the scope of the 'innovative' technologies studied.

Think critically

To what extent can the 'eco-design' of solar technologies truly achieve carbon neutrality, considering the entire supply chain and disposal process?

Design Principles

"Minimize life cycle environmental impact and cost through informed material selection, optimized manufacturing, and holistic system design."

As the demand for renewable energy solutions grows, designers and engineers must consider the full environmental and economic implications of their creations. This research provides a framework for optimizing solar technologies, ensuring they are not only effective but also sustainable and cost-competitive.

What This Means for Your Design

Making solar panels and solar power systems more environmentally friendly and cheaper involves smart choices about the materials used and how they are made, all the way from start to finish.

How to use in your project

1.Use the concept of Life Cycle Assessment (LCA) to justify material choices and design decisions, demonstrating an understanding of the product's environmental footprint from cradle to grave.
