Wang Wenjing of the Solar Cell Technology Research Division of the Institute of Electrical Engineering of the Chinese Academy of Sciences told the reporter that according to the statistics of 2009, from 2005 onwards, the growth rate of thin-film batteries was faster than that of cadmium telluride, and crystalline silicon gradually declined, giving up share. It is the growth of cadmium telluride batteries.
Cadmium telluride batteries were few before 2004, but then grew rapidly. By 2009, cadmium telluride batteries accounted for 9%. Silicon-based thin-film solar cells have not changed much in recent years, starting from 4.7% and finally rising to 6.1%.
However, Shao Jun, a partner with Dresdner Capital, still has some "views" about cadmium telluride. He believes that cadmium telluride itself is an inert gas, which will eventually be limited by the maximum conversion efficiency. Second, cadmium telluride itself is toxic. If the treatment is not strict enough, it may bring about some other negative effects.
Therefore, compared with the same, Germany with the capital tends to polycrystalline silicon solar cells, and voted for the Swiss Energy Technology Corporation (SIERRA SOLAR POWER).
In addition, gallium arsenide (GaAs) materials are also receiving attention. IMEC, a Belgium-based research institute, claims that the use of single-junction gallium arsenide (GaAs) solar cells on a silicon substrate can achieve a conversion rate of 24.7%.
"We have seen GaAs-type projects, but we have not yet grasped and can not invest." Zhang Zhong revealed to reporters.
EVA mat is a kind of foam mat for EVA sport mat, EVA Exercise Mat, and EVA training mat, made from Eco-friendly, high density, closed cell, non-smell and non-toxic EVA foam material.
The EVA mat is offered in either 60cm x 60cm size or 100cm x 100cm size. 60cm x 60cm size. With interlocking edges, the mats can be easy to connect together without any loose.
60cm x 60cm EVA mat is normally applied in room, or gym. It is easy to store, more popular for the personal exercise lovers to use at home. Also it can be a good protection for home flooring if you are intended to set up a heavy training equipment in your house.
100cm x 100cm EVA mat is also called Martial Arts Mat,
Taekwondo mat, Karate mat, Judo mat, Jiu Jitsu mat and Aikido mat, cause it is
normally applied in dojo for Taekwondo, Karate, Judo, Jiu Jitsu and Aikido training.
Also the mat is reversible with double colors, which forms a standard size
flooring for training.
