英文要約Title: Development on PV recycling system for some wide-area (FY2010-FY2014) FY2013 Annual Report

Aiming at establishment of a PV recycling system, we have started a development of low cost universal recycling processes applicable to various types of PV modules and a LCA study and proposing a social system desired for the PV recycling system. Outline of the development and the studies in fiscal 2013 are as follows.
The low cost universal recycling system developed until FY2012 consist of following processes, aluminum-frame break-up, back-sheet removing, EVA thermal processing and CIS thin layer scrapping. We have developed a system controller which synchronizes each apparatus to process every module fed sequentially. Then a lot of end-of life modules sequentially processing experiments have been conducted with the PV recycling system using several hundreds of end-of-life crystalline silicone modules. The experiments revealed a lot of points to be improved of each apparatus concretely, such as blockages of pipes which work as thermal decomposition gas translation of EVA and so on. We have performed all the improvements after the module processing experiments. In addition to the experiments, a lot of glass substrate sequentially processing experiments have been conducted with CIS metal film scrapping apparatus using more than fifteen hundreds of CIS substrate scraps from CIS module production lines. That also revealed a lot of points to be improved in the apparatus, such as the substrates break in the process, low recovery rate of CIS metal powder and so on. We have also performed all the improvements after the substrate processing experiments. Finally an after-processing apparatus for EVA thermal process have been developed to process specific modules smoothly which have two glass plates such as CIS modules. We will hereafter conduct performance tests on the total recycling system through processing more than several thousand end-of-life modules to estimate annual processing capability, stability, reliability, costs.
