스크린 프린팅을 이용한 결정질 실리콘 태양전지 소성 조건 최적화

In this paper, the firing condition among crystalline silicon solar cell fabrication processes was studied. Many studies have been performed to improve the efficiency of crystalline silicon solar cell. Both single and multi crystalline silicon wafers in p-type were used with surface area 156×156 ㎟ and resistance 0.5?2 mΩ. To find the optimized firing condition to fabricate the silicon solar cell, the five-zone belt furnace was used with changing the temperatures of the each zone. As a result, the firing condition for single and multi silicon solar cell was different and found to gain the best conversion efficiency. We achieved the energy conversion efficiencies of 17.3 % and 16.3 % for single and multi crystalline silicon solar cell, respectively.
