Project leader predicts bright future for solar cell test center
Print Edition
A SOLAR cell test center has been created by the Shanghai Institute of Microsystems and Information Technology in Jiading.
Currently, the project is applying for national approval and if this is granted it is expected to go into use next year.
The test center is a 40-square-meter enclosed draught-proofed laboratory with strictly controlled cleanliness and humidity.
At the center are two pieces of equipment — each nearly 2 meters high — emitting light and functioning as the center's very own suns.
When a beam of light is cast on the solar cell being tested, all the cell data is available to staff on their computes.
“To complete a standard test takes about half an hour, however, preparations takes around two hours to ensure the illumination intensity and indoor temperature are kept unchanged,” project leader Liu Zhengxin said.
Liu saw the need for such a solar cell test facility when he was returning to China from Japan.
Even though the market was huge and the development of the solar power industry rapid, there were almost no test facilities in China, explained Liu. “Testing technology is a guarantee for the development of the industry,” added the project leader.
Chinese enterprises have to send cell panels overseas for testing, a process that can take between two to four months. Testing at the center would save the time and money, as it can complete five standard tests in three days — equivalent to the test speed in Japan.
“Our next challenge is to recruit the right people with professional experience and English ability,” Liu said.
Liu also called for stronger management of solar cell testing from the government.
“I hope central government can produce a long-term and systematic plan on solar cell testing,” Liu added.
