ORALS - SPECIAL SESSION: CONTACTING ADVANCED INDUSTRIAL WAFER SILICON CELLS: CHALLENGES AND SOLUTIONS FOR TEST LABS AND EQUIPMENT MANUFACTURERS
Chair/Organizer: Dean Levi
Sheraton 1

As silicon PV technology advances the contact patterns on industrial wafer silicon solar cells are rapidly evolving. Multiple patterned busbars and busbar-less cells can increase efficiency and reduce cost. These changes present significant challenges for calibration labs. As contact patterns and cell interconnections in modules evolve, even the concept of Isc for STC calibration of wafers becomes blurry. Do we need to consider a new standard to ensure that wafer calibrations continue to be meaningful? Join speakers from major calibration labs, equipment suppliers, and PV manufacturers in this informal symposium to discuss challenges and solutions presented by the rapid evolution of wafer contact patterns.
