技術簡介

在屆齡或提前失效汰除的太陽能模組中，仍有許多材料具有循環再利用的價值。本技術報告首先概述太陽能模組失效模式，以及全球太陽光電裝置廢棄物量的預測趨勢，然後就模組回收處理使用的熱處理法、機械法與化學蝕刻法作評析。我們的技術是利用太陽能模組回收的矽晶電池片經適當處理成回收矽晶片後，直接再製成太陽電池片。

Abstract

There are still many valuable materials for recycling among aged and early-loss PV modules. This report first summarizes the failure modes of solar modules, as well as the forecast trends of global PV capacity and waste, and then makes a detailed analysis of the heat treatment method, mechanical method and chemical etching method used for module recycling. Our technology is to use silicon cells recovered from photovoltaic modules, process them into reclaimed silicon wafers, and then directly remake photovoltaic cells.

技術規格

以濕式化學處理模組回收之電池，最終取得回收晶片平均厚度148um (商規原生晶片＞180 um)、載子壽命1.16 us (商規原生晶片＞1 us)、再製的電池轉化效率達20.6％ (原生電池效率21.8％)。

Technical Specification

The cells taken from modules was reclaimed by wet chemical processing and the average thickness of the reclaimed wafers was 148 um (virgin industrial wafer was 180 um), carrier life 1.16 us (virgin industrial wafer was ＞1 us), and the re-manufactured cells with the best average conversion efficiency of 20.6 ％ was obtained (original cell efficiency was 21.8％).
