Hence, incorporating a thick layer of Sb2S3 in industrial CIGS solar cells can effectively reduce ... conversion efficiency of 31.15%, an open-circuit voltage of 1.08 V, a short-circuit current ...

They described their findings in “Micro-sized thin-film solar cells via area ... approach for CIGS,” the research group said. They attributed the lower open-circuit voltage of the thinner ...

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 ...

Researchers from Humboldt University Berlin and HZB have developed a tandem solar cell combining a perovskite-based top cell ...

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 ...

Such high-efficiency CIGS solar cells up to now were developed only on glass substrates with processes where CIGS layers are grown at temperatures of 600 °C or above. In contrast, polymer foils ...

OSU engineers have developed a process to create "CIGS" solar cells with inkjet printing technology that reduces raw material waste by 90 percent and significantly lowers the cost of producing ...

Researchers from Humboldt University Berlin and HZB have developed a tandem solar cell combining a perovskite-based top cell with a CIGS (copper, indium, gallium, and selenium) bottom cell. By ...

"The new record value for flexible CIGS solar cells of 18.7% nearly closes the "efficiency gap" to solar cells based on polycrystalline silicon (Si) wafers or CIGS thin film cells on glass", says ...
