a. Describe the need or problem addressed by this activity.
(Indicate the customer, what benefits they will receive, and if possible, quantify the impact on the return on investment [ROI] if the Document is implemented.)
With the development of PV technology, the demanding of solar cell quality is becoming higher. Originally, electrical performance was the only assessment of solar cell quality. Nowadays, other properties of solar cell such as exterior appearance are also included. Solar cell sorting equipment with single testing function cannot meet the demand of PV industry. The trend for sorting equipment with comprehensive testing , complete automatic classification based on appearance (such as exterior defects, color, stains, etc.) and electrical properties (such as short-circuit current, open-circuit voltage, fill factor, efficiency, power, etc.) and to reduce human intervention is inevitable. Sorting equipment with functions of testing both exterior appearance and electrical properties provides solar cell manufacturers more comprehensive quality data, which facilitates the strict control of manufacturing processes and the realization of Lean Production and Intelligent Manufacturing. Therefore, the guidance of designing such sorting equipment and specifying main performance parameters is necessary to provide high-quality product for the industry.

The resulting document is expected:
NOT to be a Safety Guideline
to be a Safety Guideline
": When all safety-related information is removed from the Document, the Document is NOT technically sound and complete - Refer to Section 15.1 of the
for special procedures to be followed.
NOT to be a Safety Guideline
": When all safety-related information is removed from the Document, the Document is still technically sound and complete.
6. Intellectual Property Considerations:
For a new Standard or Safety Guideline and for any part to be modified or added in a Revision of published Standards and Safety Guidelines
the use of patented technology is NOT required.
If "patented technology is intended to be included in the proposed Standard(s) or Safety Guideline(s) " is selected above, then also check one:
