Abstract

The recovery of copper from spent photovoltaic ribbon was conducted using thermal treatment method at the range of temperature of $300^{\circ}C$ to $600^{\circ}C$ under inert atmosphere. The coating layer consisted of lead of 68.99 wt.% and tin of 31.21 wt.% was melted down at elevated temperatures and was collected on the bottom of crucible. The chemical composition of copper ribbon after thermal treatment was analyzed by ICP-MS (Inductively coupled plasma mass spectrometry) and the purity of copper was found to be obtained up to about 96 wt.% regardless of temperatures. The cross-sectional area of the specimen was also examined by SEM (scanning electron microscopy) and EDX (energy dispersive X-ray microscopy).

폐 태양광 전지내의 구리리본전극으로부터 구리를 회수하기 위해 불활성 가스분위기하에서 $300-600^{\circ}C$로 열처리 하였다. 구리리본전극의 코팅층은 68.99 wt.%의 납과 31.21 wt.%의 주석으로 구성되어 있는데, 각각의 온도에서 코팅층을 용해한 후 반응도가니에 용해된 코팅층 회수하였다. 열처리 후 회수되어진 코팅층은 ICP-MS (Inductively coupled plasma mass spectrometry)로 성분 분석을 실시하였으며, 온도범위에 관계없이 95 wt.% 이상의 구리순도를 얻을 수 있었다. 구리리본전극 샘플의 횡단면은 SEM (scanning electron microscopy) and EDX (energy dispersive X-ray microscopy)로 관찰하였다.
