Collaboration with UCLA: Research on Perovskite-CIGS tandem solar cells yields 24.9 percent efficiency


Primarily based on a industrial CIGS photo voltaic cell, Midsummer engineers, by working with the researchers of Prof. Yang Yang laboratory on the College of California, Los Angeles (UCLA), which confirmed a four-terminal perovskite-CIGS tandem photo voltaic cell to realize 24.9 p.c effectivity.

[Los Angeles, CA, USA, March 19, 2023.] Primarily based on a industrial CIGS photo voltaic cell, Midsummer engineers, by working with the researchers of Prof. Yang Yang laboratory on the College of California, Los Angeles (UCLA), which confirmed a four-terminal perovskite-CIGS tandem photo voltaic cell to realize 24.9 p.c effectivity.

Midsummer is a number one Swedish developer and producer of skinny movie CIGS photo voltaic cells. Just lately, by way of a joint mission with Prof. Yang, they demonstrated a 4-terminal perovskite-CIGS tandem photo voltaic cell. It’s based mostly on a perovskite high cell optimized for integration with Midsummer’s CIGS cells used of their industrial suite of BIPV merchandise.

The cell exhibits an effectivity of 24.9 p.c as a 4-terminal gadget structure. It consists of an higher layer of extensive bandgap perovskite cells and a decrease layer of CIGS cells. Analysis continues with the aim of a two-terminal perovskite-CIGS cell that may make this explicit photo voltaic cell extra aggressive and appropriate for mass manufacturing.

This work exhibits the potential for constructing a tandem cell in a breakthrough manufacturing confirmed course of developed in Midsummer and utilizing the Midsummer DUO machine. The DUO manufacturing system developed by Midsummer is ready to present excessive efficiency CIGS photo voltaic cells with dimensions of 156 mm x 156 mm on a versatile chrome steel substrate. This way issue is appropriate for subsequent processing of perovskite movies within the firm’s present BIPV product suite (SLIM; WAVE; and BOLD).

“We really feel lucky to be working with Professor Yang’s group at UCLA to reveal vital advances in perovskites,” mentioned Leon Chiu, President, Pioneer Supplies, Inc. chrome steel. “Combining manufacturing of Midsummer’s confirmed CIGS processing with Yang’s Lab’s tailor-made perovskite exhibits a transparent path towards increasing the attain of BIPV by enhancing effectivity and reducing prices .”

“Perovskite-CIGS tandem cells have nice potential sooner or later and the Midsummer photo voltaic panel design has the most effective situations for constructing a industrial product for one of these photo voltaic panel, for instance as a result of it has a diode between every photo voltaic cell,” feedback Sven Lindström, CEO , Midsummer.

Professor Yang Yang quoted: “We’re completely happy to have this chance to work with Midsummer and PMI. Our final aim is to reveal two-terminal perovskite / CIGS tandem cells, appropriate for mass manufacturing.”

About Midsummer
Midsummer is a Swedish photo voltaic vitality firm that develops and sells tools for the manufacturing of skinny photo voltaic cells and in addition manufactures, sells and installs photo voltaic roofs. The photo voltaic cells are of CIGS know-how and are skinny, mild, versatile, sensible and have a small carbon footprint in comparison with different photo voltaic panels.

The photo voltaic roofs are manufactured in Sweden utilizing the corporate’s personal distinctive DUO system which has earned the place as probably the most widespread manufacturing software for CIGS renewable photo voltaic cells on the earth. The Firm’s shares (MIDS) are traded on the Nasdaq First North Development Market with G&W Fondkommission as Licensed Adviser. For extra data, please go to: midsummer.se
