Abstract

Solar Cells, Inc. (SCI) has a program to produce 60 cm×120 cm solar modules based on CdTe films deposited from high temperature vapors. Deposition techniques include close spaced sublimation and chemical vapor deposition using elemental sources. Small area efficiency has been confirmed by NREL at 9.3% on a 0.22 cm2 device (825 mV Voc, 18.16 mA/cm2 Jsc, and 0.62 FF) deposited on a 100 cm2 substrate. Preliminary work has begun on the fabrication of 8 cell, 64 cm2 submodules and 60 cm×120 cm modules. Small area devices produced on the larger substrate material have exceeded 8% efficiency.
