IMPROVEMENT OF CONVERSION EFFICIENCY FOR MULTI-CRYSTALLINE SILICON SOLAR CELLS USING POST METALLIZATION ANNEALING |
초록 |
Post metallization annealing (PMA) of crystalline silicon solar cell was carried out at various conditions of temperature, pressure, and time for as-fabricated samples. Compared with an as-fabricated sample, post-treatment annealing in pure hydrogen ambient (100% H2) at 250 oC at 5 atm improved the cell conversion efficiency. It can be attributed to significantly improved hydrogen-passivation in high concentration hydrogen process. Passivation effects are observed after annealing and evaluated using minority carrier diffusion length measurements. The results of this experiment represent a promising guideline for improving the high-efficiency solar cells by introducing an easy and low cost process of post hydrogenation in optimized condition. |
