Chinese Academy of Sciences has made new progress in heat pump electricity storage technology

With thermal storage technology, electric energy is converted into heat energy (and/or cold energy) in the form of storage, and converted into electrical energy output when needed. With advantages of high energy storage density and low cost, it is expected to become the backbone of large-scale energy storage in the future, and play an important …

Perovskite solar cells have an efficiency of 21%

As researchers around the world race to develop lead-free perovskite solar cells, scientists at the University of Manchester have developed a perovskite solar cell based on a new technology to prevent potential lead leaks. The scientists embedded the cells in a "fail-safe" system that traps lead ions. The device is made of hydroxyapatite, a naturally …

Inconvenient truth: The application of super-large current component junction box is a safety hazard

Some time ago, an article mentioned that the high current junction box has fully met the requirements of ultra-high power components and presented the data for the 25A junction box. In fact, according to the author's understanding, 25A junction box can not meet the use requirements of super-large current double-sided components. This paper will give …

The influence of tilt Angle on pv power generation is briefly described

The inclination Angle of a photovoltaic power station is the Angle between the surface of the photovoltaic module and the surface water plane. During the design of power station, the Angle with the highest radiation amount is generally selected as the best inclination design by referring to the historical data of cumulative radiation amount of …
