Are heterojunctions an emerging material?

In recent years, heterojunctions have received increasing attention from researchers as an emerging material, because the constructed heterostructures can significantly improve the rate capability and cycling stability of the materials.

How much Indium is used in a bifacial heterojunction solar cell?

The indium usage of the 27.09% efficiency record cell is only 1/5 of that of traditional bifacial heterojunction solar cells. “Innovation is the core competitiveness of enterprises and LONGi is committed to 'making the best of solar energy to build a green world'.

Are HBC cells better than bifacial heterojunction solar cells?

Another advantage of HBC cells over bifacial heterojunction solar cells is the reduced usage of transparent conductive oxide layers (ITO). Through continuous technological improvements, LONGi's R&D team has developed an ultra-thin TCO layer with reduced indium usage.

What is a rechargeable battery?

Rechargeable batteries are key in the field of electrochemical energy storage, and the development of advanced electrode materials is essential to meet the increasing demand of electrochemical energy storage devices with higher density of energy and power. Anode materials are the key components of batteries.

Are lithium metal anode batteries the Holy Grail of batteries?

“Lithium metal anode batteries are considered the holy grail of batteries because they have ten times the capacity of commercial graphite anodes and could drastically increase the driving distance of electric vehicles,” said Xin Li, Associate Professor of Materials Science at SEAS and senior author of the paper.

How will lithium-ion batteries change the world?

It is also expected that demand for lithium-ion batteries will increase up to tenfold by 2030, according to the US Department for Energy, so manufacturers are constantly building battery plants to keep up. Lithium mining can be controversial as it can take several years to develop and has a considerable impact on the environment.
