2Expert Interpretation
This article provides an in-depth interpretation of the SJ/T 12184-2026 'Perovskite Photovoltaic Modules' standard, covering scope, technical requirements, test methods, and inspection rules to help readers comprehensively understand the quality requirements and testing processes for perovskite PV modules.
Standard Overview
SJ/T 12184-2026 'Perovskite Photovoltaic Modules' is an electronic industry standard of the People's Republic of China, published on June 1, 2026, and implemented on December 1, 2026. This standard applies to glass-substrate single-junction perovskite PV modules and specifies full-process regulations from technical requirements to test methods, inspection rules, packaging, and transportation. The formulation of the standard referenced multiple international and domestic standards, such as the IEC 61215 series and GB/T 9535 series, ensuring alignment with international practices.
Core Technical Requirements
The standard sets clear requirements for module appearance, dimensions, electroluminescence, optoelectronic performance, electrical safety, weatherability, mechanical performance, and fire resistance. For example, the appearance must not exhibit defects such as film discoloration or delamination, and the quantity of internal foreign matter is limited; optoelectronic performance requires power output under standard test conditions to be no less than the nameplate rated value; weatherability requires power degradation not to exceed 5% after undergoing thermal cycling and damp-freeze tests.
Test Methods and Instruments
The standard provides detailed test methods, including appearance inspection, dimensional measurement, electroluminescence testing, performance testing under standard conditions, temperature coefficient measurement, and insulation testing. Instruments used include measuring tools with accuracy better than 1 mm, electroluminescence test systems with injection current ranges of 0.3-0.5 times the short-circuit current, solar simulators meeting specific illumination requirements, and temperature monitoring devices with an accuracy of ±2.0℃.
Test Conditions and Judgment Criteria
Test conditions include: Standard Test Conditions (STC, irradiance 1000 W/m², temperature 25℃), with light intensity not exceeding 10000 W/m² and temperature not exceeding 60℃ during stabilization treatment. Judgment criteria include power degradation not exceeding 5%, and insulation resistance multiplied by area not less than 40 MΩ·m², etc.
Comparison with Other Standards
| Standard | Scope of Application | Main Technical Requirements |
|---|---|---|
| SJ/T 12184-2026 | Glass-substrate single-junction perovskite PV modules | Appearance, dimensions, electroluminescence, optoelectronic performance, electrical safety, weatherability, mechanical performance, fire resistance |
| GB/T 9535.1-202X | General test requirements for ground-mounted PV modules | Design qualification and type testing |
| IEC 61215-1-4:2021 | Thin-film Cu(In,Ga)(S,Se)2 PV modules | Special test requirements |
Targeting the characteristics of perovskite materials, this standard adds requirements for electroluminescence and specific appearance defects, such as hollow areas and internal scratches, reflecting considerations for the uniqueness of perovskite modules.
Practical Guidance Significance
The publication of this standard provides a unified technical basis for the production, testing, and application of perovskite PV modules, helping to improve product quality and reliability and promoting the industrialization of perovskite PV technology. Enterprises should conduct factory acceptance tests and type tests in accordance with the standard requirements to ensure module performance meets specifications.
