Leader
Masaaki Yamamichi/ AIST
Takashi Ishihara/ Mitsubishi Electric
Charter
Identify standardization needs and priorities for specifications, guidelines and procedures related to Materials used for manufacturing PV cells/modules and systems.
Examples of such material include, but are not limited to: substrates, TCO films, optical enhancement films, conductive interconnect, insulator materials, absorber films, PVB, EVA, backsheet, sputtering targets, starting material e.g. UMG Si, Poly-si, etc.
Participate and support the PV Standards Roadmap discussion.
Scope
Survey PV producers, material suppliers, other SDOs (e,g, ASTM, etc.) consortia (e.g. NREL, NIST, etc.) and DOE interests to validate and prioritize the prospective materials list.
Develop a list of key players to support the TF efforts.
Find leaders for selected TF activities.
Generate a document development plan
Shared the outcome of NA and EU meetings.

9. Japan PV Materials Task Force 2/2: Doc. #5417
The SNARF of Doc. #5417 “New Standard: Test Method for Measurement of Defects in PV Silicon Wafers in PV Modules by Electroluminescence Imaging” was approved at the committee meeting on 10 April, 2012
Rationale
Defects in Si wafers in PV modules are a key parameter affecting module performance and reliability. Electroluminescence (EL) has been employed to measure in high volume module in production. However, a standardized test method for measuring defects by EL is currently not available, neither off-line nor in-line measurement. This often results in uncertain discussions about the wafer quality between suppliers and customers. The standardized test method for defects in PV Si wafers in PV modules by EL is required for improving PV module performance and reliability.
Scope
This standard defines the test method for crack measurement in PV silicon wafers in PV modules by EL imaging, including EL measurement tool setup and suggestions in interpreting measurement results. This standard does not intend to cover all kinds of defect detected by EL but crack only.
