Abstract/Summary:


An update of EPBT and greenhouse gas emissions from the life cycle of CdTe thin-film technology and bulk Si PV technologies (i.e., mono, multi-crystalline and ribbon) is presented. All technologies have improved substantially from the previous (2004-2006) estimates. CdTe PV production and recycling in Frankfurt-Oder, Germany has been investigated in detail. Furthermore, emission factors of NF3 in the production of the gas and its use in reactor cleaning in a-Si/tandem-Si PV facilities are investigated based on actual data from two production sites and six end-use facilities. These data show much lower NF3 emission factors than those previously reported.
