      Due to the depletion of fossil fuels and the use of fuels because of the industrial development, the global warming issues have arisen. Therefore, the new renewable energy for solving the environmental issues and energy depletion are receiving much attention. In particular, the photovoltaic energy is the most promising and technically matured sector in the renewable energy sector. The importance of the recycling of photovoltaic modules is increasing and many studies are being conducted on the recovery of the valuable resources from the spent photovoltaic module and the recycling of them worldwide. However, there are not many studies conducted on the recovery of the valuable metals from the spent PV ribbon in the photovoltaic module. Therefore, the recovery and recycling of the valuable metals from the PV ribbon in the spent photovoltaic module is expected to make great contribution to the localization of the economic resources. This study is recovery of valuable metals such as copper, tin, and lead from photovoltaic ribbon in spent solar module by pyrometallurgy method. Photovoltaic ribbon in the spent solar module was oxidized at the surface therefore heat treatment was conducted at a high temperature in a reducing gas atmosphere. The Photovoltaic ribbon is coated with lead and tin alloy on the copper wire. In a high-temperature reducing atmosphere, lead and tin except copper are melted and separated copper by melting point difference. The melted and separated coating layer consists of copper, lead and tin. Under high temperature heat treatment conditions, lead is separated from the coating layer by vapor deposition method and separated into high purity lead and copper-tin alloy. As a result, Copper wire, high purity lead and Copper-tin alloy are successfully separated and recovered from the photovoltaic ribbon.
