The new achievement of efficiency record of thin film which use cadmium telluride (CdTe) solar cell has been noted by the U.S. NREL with the latest efficiency of 17.3 percent by a company based in Arizona, First Solar. The company of second-largest manufacturer of Photovoltaic modules has surpassed the previous record of 16.7 percent efficiency of CdTe solar cell.
As a cheaper of production cost as much as 30 percent than CIGS solar cell,CdTe thin film technology is a solar panel semiconductor which used in film vapor deposition process and its specific chemical-combination considered as most cost effective. But besides a low price, CdTe has a disadvantages in efficiency when compared with the modules from crystalline silicon.
In fact, the lab efficiencies will not be the same after the process to make a solar module. Efforts to improve the efficiency of thin-film solar cells can be done by increasing the surface area of solar cell although the result is less efficient for installation in narrow spaces.
The first green wise step is also performed by First Solar to provide recycling programs as well as prefunded solar module collection. Solar modules which discarded by the consumer will be recycled up to 90 percent for their new products. Customers do not need to pay a bit for collection at any time.
