Mg x Zn1- x O (MZO) shows great promise to replace CdS as a buffer layer in CdTe-based solar cells. It is more transparent, and the MZO bandgap and electron density can be tuned, thus providing flexibility in controlling the conduction band offsets a

A major challenge in the fabrication of high band gap II–VI polycrystalline solar cells is to preserve the original composition of the absorber after the CdCl2 activation treatment. In this study, a method is demonstrated to maintain the Cd-Zn-Te a

CdTe thin film solar cells have demonstrated efficiencies over 20%, but CdTe has a somewhat higher band gap than optimal for single-junction terrestrial solar-cell power generation. A reduction in the band gap could therefore result in an overall imp

Increasing doping density in CdTe absorbers remains one of the most promising avenues for increasing the open-circuit voltage $\mathrm{(V_{OC})}$ of photovoltaic devices. This work aimed to develop methods for quickly incorporating group V as a p-typ

The main obstacle to realizing the use of polycrystalline wide bandgap alloys of CdTe with Mg and Zn in PV is the CdCl 2 processing step. This step, essential to CdTe device performance, removes Zn and Mg from the alloy films while producing less of

There are two major hurdles in the fabrication of top cell using polycrystalline films of CdTe alloys. First, the deposition of the films is difficult due to the difference in the vapor pressure of the individual elements present in the alloy or long

The addition of a CdMgTe (CMT) layer at the back of a CdTe solar cell should improve its performance by reflecting both photoelectrons and forward-current electrons away from the rear surface. Higher collection of photoelectrons will increase the cel

A hollow-cathode plasma-cleaning source, designed for uniformity, was added to the load-lock region of an existing single-vacuum CdTe-cell fabrication system. This plasma source cleans the transparent-conductive-oxide layer of the cell prior to the d

In this study Cd 1−x Mg x Te thin films are investigated for use as an absorber layer for future use in top cells of a tandem device. An essential step in the development of this new absorber layer is the passivation process. An experimental passiv
