Technical FAQs 3

What is a perovskite/CIGS tandem solar cell?

** Perovskite/CIGS tandem solar cell: A two-layer thin-film solar cell combining two different types of solar cells that absorb different wavelength ranges of slight energy. This configuration can generate more electricity than conventional single-junction cells, making it a strong candidate for next-generation PV technology.

Is South Korea a leader in next-generation photovoltaic (PV) systems?

A team of South Korean researchers has set a new world record in power conversion efficiency* for perovskite/CIGS (copper indium gallium selenide) tandem solar cells**, demonstrating the country’s technological leadership in next-generation photovoltaic (PV) systems.

Are thin-film perovskite/CIGS tandem solar cells a viable alternative?

In this context, thin-film perovskite/CIGS tandem solar cells offer a highly promising alternative. Their lightweight and flexible nature allows them to be applied like stickers to a variety of surfaces—including building exteriors, windows, car roofs, and soundproof walls—thus maximizing land use efficiency.
