Thin-Film CdTe and CuInSe2 Photovoltaic Technologies

    Research output: NRELTechnical Report


    Total-area conversion efficiency of 15%-15.8% have been achieved for thin-film CdTe and CIS solar cells. Modules with power output of 5-53 W have been demonstrated by several groups world-wide. Critical processes and reaction pathways for achieving excellent PV devices have been elucidated. Research, development and technical issues have been identified, which could result in potentialimprovements in device and module performance. A 1-kW thin-film CdTe array has been installed and is being tested. Multimegawatt thin-film CdTe manufacturing plants are expected to be completed in 1-2 years.
