Longi unveils heterojunction BC solar cells with 27.3% efficiency
The Chinese manufacturer said the device is based on dense passivating contacts that reduce parasitic light absorption and improve passivation. It used a streamlined manufacturing technique that is reportedly about one-third more effective than TOPCon mainstream technology.
First Solar warns global solar manufacturers of patent infringement
The U.S. solar panel manufacturer has sent letters to Longi, Trina Solar, Jinko Solar, JA Solar and Canadian Solar saying it believes the companies are infringing on its patents.
Softbank, Longi develop 665 g/m2 heterojunction solar modules with 22.2% efficiency
Researchers from the two companies have built a lightweight and flexible silicon heterojunction (HJT) PV panel that measures 563 mm x 584 mm and weighs just 218.5 g.
JinkoSolar, Trina say TOPCon modules outperform p-type back-contact panels
JinkoSolar and Trina Solar have separately reported that on-field testing shows tunnel oxide passivated contact (TOPCon) solar modules outperform p-type back-contact PV modules in monthly power generation.
Longi introduces 665 W HPBC photovoltaic modules
The Chinese PV manufacturer said its new module series has a power conversion efficiency of up to 24.8% and temperature coefficient is -0.26% per C.
Longi, ANU develop gettering-based process to improve n-type wafer quality
The Chinese module maker and the Australian National University utilized phosphorus diffusion gettering and another defect mitigation strategy to improve the quality of n-type wafers. The proposed process contributed to improve the material quality especially towards the tail-ends.
Longi achieves 34.6% efficiency for two-terminal tandem perovskite solar cell prototype
In a paper published in nature, the Chinese module maker explained that the 33.9%-efficient tandem device it unveiled in December 2023 is based on a bilayer intertwined passivation strategy that combines efficient electron extraction with further suppression of nonradiative recombination. It also revealed that its two-terminal tandem prototype devices achieved an efficiency of 34.6%.
