While researchers have improved silicon - based cells almost to their theoretical limit, there is significant room for efficiency improvements
for cadmium telluride, which could be bettered by an additional 30 percent, said Lynn.

It uses
cadmium telluride for its thin - film PV panels, so the tariffs, which specifically concern the more popular crystalline silicone solar products, won't affect it.
«America is quickly falling behind in clean energy, trading Middle Eastern oil
for cheap Chinese solar, batteries and wind turbines,» says Chris Rivest, co-founder of Berkeley, Calif. — based SunPrint, which is developing technology to print
cadmium telluride thin - film photovoltaic cells.
Yet,
cadmium telluride commands only about 30 percent of the thin - film market, according to DoE statistics, compared with amorphous silicon cells (such as those produced by Sharp and ECD Ovonics), which account
for more than 60 percent; CIGS cells make up just about 1 percent of this market.
For example, Tempe, Ariz. — based First Solar, Inc., which employs cadmium telluride in its thin - film solar cells, sells its modules encased in glass for either large arrays or roofto
For example, Tempe, Ariz. — based First Solar, Inc., which employs

for either large arrays or rooftops.
Already, such issues have driven major companies such as General Electric to opt
for competing technologies, investing in thin - film solar cells made from
cadmium telluride by PrimeStar.
For their outstanding contribution in the field of crystals of
cadmium - mercury -
telluride (CMT) leading to the application of detectors made from CMT to the successful development of thermal imaging.
Researchers improved the maximum voltage available from a
cadmium telluride (CdTe) solar cell, overcoming a practical limit that has been pursued
for six decades and is key to improving efficiency.
Early last year, «Rumor: First Solar Looks to Experiment With CIGS» by Michael Kanellos
for Greentech Media speculated CdTe (
cadmium telluride) expert First Solar was investigating the CIGS (copper indium gallium diselenide) material set
for potential PV commercialization.
Indiana energy holding company Vectren Energy Delivery (Vectren), has selected First Solar, Inc. to construct the 50 - megawatt (MW)
cadmium telluride (CdTe) thin - film solar array sketched out last month as part of Vectren's long - term plan
for electric generation.
If the solar industry has become dependent on the short - term low - cost
cadmium telluride option, long - term scarcity could end up moving solar electricity back out of grid parity
for many people.
If production of
cadmium telluride solar panels increases substantially, it could trigger a scarcity of tellurium, raising the price
for that type of panel.
For instance,
cadmium telluride thin film panels could help solar reach grid parity sooner than silicon panels could, but tellurium — a key ingredient — is fairly rare.
Today the manufacturer appears to produce its
cadmium telluride modules predominantly
for its own projects in the multi-megawatt segment in the USA and Asia.
In related news, First Solar just recently reported that it had set a new world record
for cadmium -
telluride (CdTe) photovoltaic (PV) module conversion efficiency, something which should further help the well - regarded solar company continue to be a market leader.
