The 28.6% efficiency rating was certified by the CalLab at the Fraunhofer Institute for Solar Energy Systems (ISE).

Perovskite solar cell researcher Oxford PV has unveiled a new perovskite-silicon tandem module in conjunction with German module producer Sunmaxx, with a record conversion efficiency of 26.6%.

Silicon-based tandem solar cells and modules are expected to enter commercial production in 2027 with a module efficiency of 27%, according to the latest International Technology Roadmap for Photovoltaic (ITRPV) published by German engineering association VDMA.

Scott Graybeal, CEO of Caelux, writes on the market opportunity for perovskite development in the US, along with its challenges for market implementation.

Perovskite-on-silicon PV modules are more environmentally advantageous than conventional silicon heterojunction (HJT) modules over a 25-year lifetime, according to a study from researchers in Germany.

Researchers at the Fraunhofer Institute for Solar Energy Systems (ISE) have laid claim to a new solar cell efficiency record of 47.6%.

Radovan Kopecek and Joris Libal analyse recent efficiency announcements against the backdrop of new and emerging solar PV technologies, and plot the course for solar’s next steps.
