Indoor perovskite solar cell based on self-assembled monolayers achieves 42% efficiency
Researchers in Taiwan have developed an efficient carrier transport and defect passivation approach at the nickel oxide/perovskite interface in perovskite solar cells, enabling devices with 42% efficiency under indoor lighting conditions, and over 20% in simulated sunlight.
Longi Green Energy sets world record for solar module efficiency at 25.4%
China’s Longi Green Energy has set a new world record for crystalline silicon solar module efficiency with its independently developed hybrid passivated back contact (HPBC) 2.0 module, achieving a conversion efficiency of 25.4%, according to a certification report from Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE).
‘TOPCon technology comes with three or four relevant risks that should be known’
The results of this year’s Kiwa PVEL scorecard have shown that TOPCon technology is more vulnerable than PERC, and the failure rate at BOM level has increased to 41%, the highest in history, according to the testing lab.
The critical role of battery recycling in sustaining electronics and EV growth
While electronics and EV growth is a boon, it also underscores the need for sustainable growth and practices. Battery recycling is a key component of this sustainability, with environmental, economic and social benefits.
Navigating solar panel supply challenges through digitalization
High interest rates, excess warehouse inventory, and falling component prices have created a perfect storm for solar distributors since October 2023. BayWa re Solar Trade CEO Frank Jessel explains how the industry can embrace true digitalization to better navigate this volatility.
JinkoSolar announces new TOPCon solar modules with efficiency of 24.8%
The Chinese manufacturer said the new Tiger Neo 3.0 modules are available in two versions with outputs of 495 W and 670 W.
GFCL EV raises INR 1,000 crore to scale its battery materials capacity
GFCL EV will utilize the funds to scale its battery material capacities as it looks to capitalize on large-scale global opportunities in the electric vehicle and energy storage system space.
Solplanet launches 350 kW solar inverter for large-scale PV installations in India
Solplanet has introduced its ASW350K-HT three-phase solar inverter with a power of 350 kW and maximum efficiency of 99.01 % for utility-scale PV projects.
Trina Solar sues Canadian Solar for alleged TOPCon patent infringement
Trina Solar has filed a lawsuit against Canadian Solar in a US court, claiming patent infringement on an unspecified tunnel oxide passivated contact (TOPCon) solar cell technology.
Solving the UV problem of n-type solar
Laboratory testing has revealed that some negatively-doped, “n-type” tunnel oxide passivated contact (TOPCon) and heterojunction (HJT) solar modules are susceptible to ultraviolet (UV) light-related damage and degradation. That could mean trouble down the line, if modules in the field begin to show UV-related performance loss. Manufacturers are implementing solutions at cell and module level.
