This paper details the laboratory processes used to fabricate CdS/CdTe solar cells at the National Renewable Energy Laboratory. The basic fabrication technique includes low-pressure chemical vapor deposited SnO2 , chemical-bath deposited CdS, close-s
Chemical reactivity of CdCl2 wet-deposited on CdTe films studied by X-ray photoelectron spectroscopy

The authors use X-ray photoelectron spectroscopy to investigate the chemical reactivity of CdTe films exposed to a solution of CdCl2 dissolved in methanol. They show that annealing in vacuum does not instigate a chemical reaction between CdCl2 and Cd

The formation of CdTe thin films by spray deposition using nanoparticle colloids has been investigated. Employing a metathesis approach, cadmium iodide is reacted with sodium telluride in methanol solvent, resulting in the formation of soluble NaI an

A commonly used process for forming low-resistance contacts to thin-film p-type CdTe involves the formation of a Te layer by etching the CdTe film in a concentrated mixture of nitric and phosphoric acids. The authors compare evaporated Te back contac

Forty four fetuses with multicystic dysplastic kidney (MCDK) disease recognised on antenatal ultrasound were studied prospectively. In nine aborted fetuses and in five who died in the neonatal period the MCDK disease was bilateral or there were assoc

A novel semiconductor device processing technology is described that uses optical energy of a preselected spectrum to produce local melting at an illuminated semiconductor-metal (S-M) interface. This local melting results in an alloyed ohmic contact

Studies of junction photoluminescence in CdTe/CdS solar cells reveal that back-contact application produces a dramatic qualitative change in the junction PL spectrum. Prior to contact application, the spectrum has two peaks at energies of 1.508 eV an

Impurities in cadmium sulfide (CdS) films are a concern in the fabrication of copper (indium, gallium) diselenide (CIGS) and cadmium telluride (CdTe) photovoltaic devices. Films of CdS grown using chemical bath deposition (CBD) generally yield better

An unusual processing scheme has been developed for preparing single-phase cadmium stannate (Cd/sub 2/SnO/sub 4/ or CTO) films. Cd/sub 2/SnO/sub 4/ transparent conducting oxide (TCO) films have several significant advantages over conventional TCOs wh

Conference Record of the Twenty-Eighth IEEE Photovoltaic Specialists Conference - 2000 (Cat. No.00CH37036).
CdS/CdTe devices processed with ZnTe:Cu/Ti back contacts are studied as a function of contact deposition temperature between /spl sim/200/spl deg/C and /spl sim/400/spl deg/C. Both the open-circuit voltage (V/sub oc/) and fill factor (FF) increase wi
