Of cdte thin film latest news
· Currently, CdTe thin film is deposited by physical techniques such as CSVT, sputtering, electrodeposition, and spray pyrolysis. It is known that the CdTe films need a thermal treatment of CdCl 2 to improve the morphology and to reduce the recombination centers . Other treatment is with fluorine .
Alexander P. Kirk, in Solar Photovoltaic Cells, 2015 5.3 Scalability of cadmium telluride-based PV. Now, we will consider CdTe thin-film cells.The world record CdTe module efficiency as of June 2014 is 17.5% .If we assume 20% efficient modules (P out = 0.020 W cm −2 at 25°C under the AM1.5G 1× spectrum) with just 1 μm thick films, the amount of CdTe (ρ CdTe = 5.86 g cm −3) required ...
· Dr. Rinck adds: “The CdTe thin-film technology by CNBM will meet the high demands of the market even more in the future through the use of new coating equipment.” The production capacities for CdTe and CIGS solar modules in China are set to increase substantially in the coming years. CNBM plans additional investments at several sites in China.
production of CdTe solar panels with size of 0.6 m x 1.2 m and 1.2 m x 1.6 m. A CSS growth model is a useful tool to guide the CdTe thin film deposition and the design of CSS. In this paper, a growth model was developed for CdTe deposition including diffusion limited, sublimation limited and reaction limited with the presence of oxygen.
· Various university, research and commercial solar companies involved with cadmium telluride (CdTe) thin-film solar panel manufacturing have formed the U.S. Manufacturing of Advanced Cadmium Telluride (US-MAC) photovoltaics consortium.. Led by the Wright Center for Photovoltaics at The University of Toledo, Colorado State University (CSU) and the U.S. Department of Energy’s …
· Thin film solar cells based on CdS/CdTe hetero-structure has shown a drastic improvement changing from 16.5 to 22.1% efficiency during a short period of time from ~2013 to ~2016.
