12 Facts About CIGS panel

CIGS panel is one of three mainstream thin-film photovoltaic technologies, the other two being cadmium telluride and amorphous silicon.

However, as all of these technologies normally use high-temperature deposition techniques, the best performance normally comes from cells deposited on glass, even though advances in low-temperature deposition of CIGS panel cells have erased much of this performance difference.

In 2013, the market share of CIGS panel alone was about 2 percent and all thin-film technologies combined fell below 10 percent.

CIGS panel cells continue being developed, as they promise to reach silicon-like efficiencies, while maintaining their low costs, as is typical for thin-film technology.

Prominent manufacturers of CIGS panel photovoltaics were the now-bankrupt companies Nanosolar and Solyndra.

Unlike conventional crystalline silicon cells based on a homojunction, the structure of CIGS panel cells is a more complex heterojunction system.

The record efficiencies for thin film CIGS panel cells are slightly lower than that of CIGS panel for lab-scale top performance cells.

In 2008, CIGS panel efficiency was by far the highest compared with those achieved by other thin film technologies such as cadmium telluride photovoltaics or amorphous silicon .
