提出了一种从x-Si光伏组件中经济地回收硅片的方法。由于硅片成本估计约为硅光伏组件总材料成本的一半，因此回收利用可能具有经济效益。此外，回收硅PV模块允许回收玻璃基板并防止从晶片接触和互连系统处置潜在危险材料，例如银和铅。从报废器件回收硅晶片的主要问题是将晶片与伊娃聚合物封装材料干净地分离。本文介绍了在惰性气体气氛中热分解伊娃后，功能x-Si PV电池的成本效益回收。处理成本估计为每10厘米/spl次/10厘米回收电池0.20美元。
A method of economically recovering silicon wafers from x-Si PV modules is presented. Since the wafer cost is estimated at about half the total material cost of a silicon PV module, there may be economic benefits from recycling. In addition, recycling silicon PV modules allows reclamation of the glass substrate and prevents disposal of potentially hazardous materials such as silver and lead from the wafer contact and interconnect systems. The major problem for recycling silicon wafers from end-of-life devices has been cleanly separating the wafers from the EVA polymer encapsulating material. This paper describes the cost effective recycling of functioning x-Si PV cells after thermal decomposition of EVA in an inert gas atmosphere. Process costs are estimated at US $0.20 per 10 cm/spl times/10 cm recovered cell.
