Properties of CIGS Technology

Conversion efficiency

One of the most remarkable aspects of CIGS technology, or Copper Indium Gallium Selenide, is its conversion efficiency. As of 2023, CIGS solar cells have achieved efficiencies exceeding 23.4% in laboratory tests. I find it impressive that these panels can perform significantly better than many traditional silicon panels, which typically max out around 20-22%. This increased efficiency means I can generate more energy from the same surface area, making them ideal for urban settings.

Impact on the environment & recycling

Regarding environmental sustainability, the impact of CIGS technology is encouraging. The materials used in CIGS production can be sourced more abundantly than those used in other technologies, such as cadmium telluride (CdTe). I appreciate that CIGS panels can be almost entirely recycled—up to 95%—which lowers their overall environmental footprint. This circular approach aligns with my belief in a sustainable future and how crucial it is to minimize waste.
