  • UtmoLight has reported 20.7% steady-state efficiency for its perovskite solar modules 
  • It is an improvement over 19.5% efficiency the manufacturer reported last year on an 810 cm² size 
  • The company aims to transplant the technical process deployed for the efficiency improvement to larger-sized modules 

Wuxi UtmoLight, the Chinese perovskite manufacturer, has announced ‘a new world record’ for steady-state efficiency on large-size perovskite solar modules. It has achieved 20.7% efficiency on an 810 cm² module. 

It claims a certification to this efficiency level by China’s National Photovoltaic Industry Measurement and Testing Center. This is an improvement over the company’s previous high of 19.5% on the same size module announced in late-2023 (see China Solar PV News Snippets). 

UtmoLight says it significantly improved the crystallization of perovskite films by regulating the stress of the perovskite bulk phase and interface during the process of film formation, without sharing other details. 

The Chinese company has been making news for its efforts in establishing industrial production of perovskite modules. Currently operating a 150 MW line in China, it aims to expand to a GW-scale perovskite PV production line. 

UtmoLight says the 20.7% efficiency helps it lay a solid technical foundation for the process improvement of its pilot line and the world’s 1st GW-level mass production line to be completed in 2024. 

In the future, it aims to transplant this technical process to larger-sized perovskite modules. 

The company says, “In 2024, its technology advancement goals are: the steady-state efficiency of 30*30 cm² small-scale test modules exceeds 21%, and the efficiency of 0.72 m² commercial-sized modules exceeds 20%, which will be produced on the GW-level mass production line that will be put into production in the third quarter.” 

Earlier this year, UtmoLight announced the appointment of EPFL Professor Mohammad Khaja Nazeeruddin as the company’s chief scientist to help guide the manufacturer’s industrialization efforts (see Chinese Perovskite Company Appoints Chief Scientist).  

Recently, China’s Nanjing University reported 24.5% all-perovskite tandem solar module efficiency on an aperture area of 20.25 cm². It claims this to be the world’s highest efficiency for this category (see ‘New World Record’ For All-Perovskite Tandem Solar Modules).
