It's cheaper to make «thin - film solar cells»
with cadmium telluride than with silicon.
The 1.2 x 2 meter modules are expected to become commercially available at 420 - 445 watts with efficiencies of over 17 %, which is a testament to the thin film solar maker's remarkable progress
with cadmium telluride PV.
Not exact matches
While most of its peers make silicon - based panels, First Solar manufactures thin - film panels made
with cadmium -
telluride, which absorbs more frequencies of light and uses fewer materials.
Cadmium -
telluride, however, has an advantage over silicon because it can absorb the same amount of sunlight
with 98 percent less semiconducting material, thus reducing the overall cost of the solar panel.
With this data, they analyzed two solar cell materials: silicon (commonly used in solar cells) and
cadmium telluride (thin - film competitor material).
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.
The team has shown that its nickel oxide film is compatible
with many different kinds of semiconductor materials, including silicon, indium phosphide, and
cadmium telluride.
At SkyPower, we will not use panels manufactured
with toxic or rare materials, including
cadmium telluride.
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.
The company expects to resume full production by year - end
with cadmium -
telluride panels that will be able to convert 12.5 percent to 13 percent of the energy in sunlight into electricity.
The researchers investigated 4 types of solar cells: multi-crystalline silicon (
with an efficiency of 13 %), mono - crystalline silicon (14 %), ribbon silicon (11.5 %), and thin - film
cadmium telluride (9 %).
