Stable a-Si:H Based Multijunction Solar Cells with Guidance from Real Time Optics: Annual Report, Phase I: 17 July 1998-16 October 1999
This summary describes tasks of novel improved intrinsic materials for multijunction solar cells, insights into improved stability in materials and solar cells, optimization of solar cell performance with improved intrinsic layers, and optimization of multijunction solar cells. The report characterizes a protocrystalline a-Si:H film growth regime where thin samples retain their amorphous state when their growth time or thickness is limited to small values, even when films are deposited with high hydrogen dilution that results in microcrystalline thick films. The Staebler-Wronski degradation kinetics of films and devices are systematically studied as a function of hydrogen dilution.
