Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Uses an industrially relevant textile lamination process.
- +Employs a standardized laundry testing method (ISO 6330:2012).
- +Compares performance using quantitative (efficiency measurements) and qualitative (visual inspection) methods.
Limitations
The study only tested one type of solar cell and one encapsulation method. Real-world conditions might involve different washing detergents, temperatures, or machine types.
