DR RON SINTON, President & Senior Scientist – SINTON INSTRUMENTS | Topic: Optimized Production Self Testing for High Efficiency Cells
Production cell testing is often used to assign wafers into efficiency or current bins. With the introduction of new high-efficiency solar cell designs into production, there are new requirements for measurements of cells with high capacitance and bifaciality. The ideal production cell tester will bin cells, accurately measure high capacitance cells, have very-high throughput, have exceptional repeatability and reproducibility, identify the production variations that are limiting the power out of the cells, and be available at low cost. This talk will present examples of the current state of the art for these requirements.
