Enphase Energy announces IQ Microinverters across India

The U.S. headquartered inverter company has mentioned that the new Enphase IQ microinverter enables faster installation and reduce maintenance costs for installers. Moreover, new technology will produce 18% more power and will be 31% lighter and 15% smaller than the current M-Series microinverters.

Australian researchers unveil new sodium-ion battery design

Scientists from the University of Wollongong in Australia have developed battery cells based on sodium-ion technology which the university says can achieve excellent cycling stability and easily be scaled up to mass production.

SERIS researchers develop new multi-cSi texturing technique

Scientists from the Solar Energy Research Institute of Singapore (SERIS) have announced the development of a new wet chemical process to allow multi-crystalline Si wafers to be cut with diamond wire saw technology, and subsequently textured to reduce their reflectivity.

A multi-layered battle

Lamination innovation: The ongoing ambition of laminator manufacturers is to develop machines that can deliver high output through a faster lamination process, while simultaneously reducing their footprint by combining several machines into one. However, an in-depth process know-how is essential in order to produce defect-free modules. Which players possess such knowledge?

Let’s mitigate LID & LeTID!

Cell degradation: LID in p-type monocrystalline PERC cells has caused serious issues in PV plant performance. Now, it can be prevented with regeneration processes or by replacing boron with gallium. The cause of LeTID in multicrystalline PERC cells, meanwhile, is still a mystery, but researchers have proposed an industrial solution to address it.
