LED Manufacturing Cost Models for 2003, 2012, and 2020

Excel files contain bottom-up cost models for GaN-based white light-emitting diodes (LEDs). The models cover the commercial origins of the technology around the years 2003, 2012, and 2020. The data was compiled by Michael Weinold of ETH Zurich for a research project funded by the Alfred P. Sloan Foundation.

Use Cases

• Analyzing historical manufacturing cost trends for LEDs based on the three distinct model years
• Modeling the impact of inputs like electricity and clean room costs on LED production expenses
• Studying the relationship between government investment and technology innovation in the energy sector
• Comparing bottom-up cost structures for a key technology across different commercial maturity stages

Strengths

• Provides cost models for three distinct years (2003, 2012, 2020), enabling longitudinal analysis
• Includes a separate file with model inputs covering factors like electricity and clean room costs
• Archives the original U.S. Department of Energy cost model, providing provenance
• Compiled as part of a funded research project from a reputable institution (ETH Zurich)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment for large-scale ML tasks
• Last update date is unknown; freshness unverified
