China's first CIGS solar integrated power circuit

At the 6th Asia Solar Photovoltaic Industry Exhibition, which took place earlier this month in Shanghai, the exhibits included what is claimed to be China’s first copper indium gallium selenide (CIGS) solar integrated power circuit, which was developed by Henan Yanyuan Photovoltaic Technology Co Ltd with the technical support of Peking University (PKU).

According to Henan Yanyuan Photovoltaic Technology and PKU, people are familiar with solar collectors and solar cells, but are often unaware of the combination of these two elements – the solar integrated power circuit, a new type of CIGS solar cell application.

“The application of CIGS solar cell is going to be the development trend in the solar industry. It reduces pollution and costs compared with the old material, which is mainly silicon. Moreover, it’s cheaper and more efficient,” said professor Gan Zizhao of the PKU School of Physics (and an academician of the Chinese Academy of Sciences).

Zizhao added that the PKU research team had independent intellectual property of this technology, but compared with countries like the US and Germany, they are still at an intermediate level, having a long way to reduce the gap. However, there are large potential markets for this innovation in China.
