A new record for electrical energy generation from CIGS solar cells has been reached. Scientists have achieved a 23.64 percent efficiency. Uppsala University is the new world record holder for ...

New record for CIGS perovskite tandem solar cells Date: February 4, 2025 Source: Helmholtz-Zentrum Berlin für Materialien und Energie Summary: Combining two semiconductor thin films into a tandem ...

An international group of scientists has proposed a new copper indium gallium selenide (CIGS) solar cell structure using antimony trisulfide (Sb2S3) as the back surface field (BSF) layer. Sb2S3 is ...

T he Korea Institute of Energy Research has successfully developed ultra-lightweight flexible perovskite/CIGS tandem solar cells and achieved a power conversion efficiency of 23.64%, which is the ...

These scientists have developed an ingenious technique to overcome a major obstacle: the roughness of the CIGS layer. They successfully created tandem solar cells that are both efficient and durable.

The Yuma 200W CIGS solar panel is made up of copper indium gallium selenide (CIGS) solar cells, which are more flexible. They can maintain a stable output even in the shade or if sections of the ...

“In traditional high-efficiency CIGS thin-film solar cells, a relatively thick ZnO layer , with a thickness of 200−300 nm, is commonly employed as the window layer,” Regmi explained.

Swedish thin film solar cell company Midsummer has demonstrated a tandem thin-film solar cell that hits 24.9% efficiency. Midsummer makes CIGS (copper indium gallium selenide) solar cells, and it ...

For this to succeed, the material must be able to absorb an optimal portion of sunlight while avoiding wasting this energy by converting it into heat within the solar cell. CIGS solar cells consist of ...
