Uppsala University Breaks Record in Solar EfficiencyNew Efficiency Peak for CIGS Solar Cells Achieved

Uppsala University has now set a world record for energy conversion efficiency in copper indium gallium selenide (CIGS) solar cells, reaching an unprecedented 23.64% efficiency. This achievement has been validated by an independent institute, with the details published in Nature Energy.

The breakthrough was made possible through a collaboration between the First Solar European Technology Center (formerly known as Evolar) and the solar cell research team at Uppsala University. "The measurements we conducted ourselves align with the independent institute's results, confirming the accuracy of our measurement techniques," explained Marika Edoff, Professor of Solar Cell Technology at Uppsala University and the lead researcher of the study.

This is not the first time Uppsala University has made headlines for its solar cell efficiencies; the institution previously set the record in the 1990s and has consistently produced results close to the top. "Although it's been a while since we last held the record, our focus on scalability and process efficiency has always kept us at the forefront," Edoff added.

With solar power's share of global electricity exceeding 6% in 2022, the quest for more efficient solar cells at cost-effective production rates continues. The highest-performing crystalline silicon solar modules currently convert more than 22% of sunlight into electric power, demonstrating the potential for further advancements in solar technology.

  • The world record of 23.64% efficiency was independently verified by Fraunhofer ISE in Germany, showcasing the significant advancements in CIGS solar cell technology.
  • CIGS solar cells are characterized by their multiple-layered structure on a glass sheet, with a sunlight-absorbing layer composed of copper, indium, gallium, and selenide, among other elements. The optimal combination of these materials is crucial for maximizing efficiency.
  • "This world record is a milestone for Uppsala University and the First Solar European Technology Center, highlighting the reliability and potential of CIGS technology for innovative applications, such as tandem solar cells," stated Edoff. The research team's comprehensive analysis aims to further improve solar cell performance.

The researchers' commitment to pushing the boundaries of solar cell efficiency is evident in their meticulous study, which not only sets a new standard for CIGS technology but also opens the door to future innovations in the field of renewable energy.
