Perovskite solar module manufacturer Mellow Energy has announced a new record for its integrated flexible perovskite solar module. Certified by the National Institute of Metrology of China, the module achieved an output power of 86.90 W and an efficiency of 17.38% over an area of 0.5 m². The test results showed no hysteresis in forward and reverse scans, and the MPPT test exhibited almost no degradation over 300 seconds.

Mellow Energy claims this to be the highest certified efficiency for a large-area flexible perovskite module known to date. The company further highlighted that the module is produced using an integrated molding process, eliminating the need for splicing, which results in better aesthetics and high reliability.

China-based PV energy application development company Mellow Energy has announced that its perovskite-silicon 4-terminal tandem module, developed in collaboration with Zhuhai Hongjun New Energy, has successfully passed China Photovoltaic Testing Center (CPVT) certification. 

The module reprotedly achieved a front-side efficiency of 24.68% and a back-side efficiency of 18.87%. The company says that this module benefits from dual light-absorbing layers, with a theoretical efficiency limit of up to 45%.

Mellow Energy has announced the launch of what it refers to as "the world’s largest integrated flexible perovskite photovoltaic (PV) module" from its 100MW-scale production line. The module measures 1.2×1.6 square meters and weighs approximately 2.04 kilograms.

According to Mellow Energy, tests conducted by TÜV Rheinland, an internationally renowned testing and certification body, have confirmed that the 1.2×1.6-square-meter double-glass module achieves a full-area efficiency of 17.9% under standard testing conditions.

Researchers from China's Jinan University, University of Macau, Wuyi University, Guangdong Mellow Energy and Germany's IEK-5 Photovoltaik (Forschungszentrum Jülich) recently designed a two-terminal perovskite-silicon tandem solar cell that utilizes new hybrid interconnecting layers to reduce recombination losses in the top perovskite device. The tandem cell achieved an impressive fill factor of 81.8%, which the scientists said is the highest value ever reported for this cell technology to date.

The team's 2T perovskite-silicon tandem solar cell is based on special hybrid interconnecting layers (ICLs) that prevent direct contact between the perovskite absorber and transparent conductive oxide (TCO). The scientists' approach is based on sputtered nickel oxide (NiOx) as the seed layer of SAMs to build the hybrid interconnecting layers. The sputtered treatment technique provides, according to the team, an easy coating on a complex substrate and high reproducibility.
