Investigation of Deep Impurity Levels in CdTe/CdS Solar Cells

We have studied deep impurity levels of CdTe/CdS solar cells by capacitance-voltage (C-V), deep-level transient spectroscopy (DLTS) and time-resolved photoluminescence (TRPL).

Thin-Film CIGS Photovoltaic Technology: Annual Technical Report-Phase II, 16 April 1999-15 April 2000

A summary of Energy Photovoltaics' Phase II work includes the following: (1) EPV has demonstrated that it can sputter a Mo back-contact capable of supporting very high efficiency cell processing. Using EPV Mo, NREL has deposited a 17.1% CIGS cell (no AR coating). EPV believes it can identify the signature of ``good'' Mo. The Mo was produced on EPV's 0.43 m{sup 2} pilot-line equipment; (2) EPV has performed compound synthesis for several classes of materials, namely non-Cu precursor materials, C… more
