For preparation of Cadmium sulfide
(CdS) nanoparticles, cadmium chloride (CdCl2 99%, Sigma) and Sodium Sulfide (Na2S 99%, Merck) were used as received.

Electronic photocells using solid-state, silicon phototransistors that do not lose sensitivity can be used to teplace cadmium sulfide
He first coats glass with a transparent conductive tin-oxide layer and follows that by depositing cadmium sulfide
with a solution-growth (precipitation) process.
The most preferred light emitting material for semiconductors is indium gallium nitride, though other materials such as cadmium sulfide
and cadmium selenide also are used for emitting visible colors.
In particular, cadmium sulfide
(CdS) is an excellent photosensitive material and has a direct band-gap ([E.sub.g]) of 2.42 eV.
Inside a quartz furnace, the researchers grew pillars of electron-rich cadmium sulfide
on aluminum foil, in which geometrically distributed pores made by anodization served as a template.
The multi-layer stack contains molybdenum, CIGS, cadmium sulfide
, zinc oxide, and indium tin oxide, and boasts an efficiency conversion of 10%.
Some of these proteins attract cadmium sulfide
particles, while others bind bits of zinc sulfide.
Bevin Lorraine Hutcheson, 16, and Paul James Sagona, 17, both from Crestwood High School in Sumter, South Carolina, won the top ISEF award for teams in the Engineering category for their project, called Active Solar Tracker Cadmium Sulfide
Photo Conductive Cells Sensor Tracking System.
