Technology and R&D

Underlining India’s commitment to becoming the global renewable energy leader, Shri Anand Kumar, secretary of the Ministry of New and Renewable Energy, said the country plans 500 GW of capacity by 2030. He also underlined plans to become a solar and storage manufacturing hub; and said the International Solar Alliance needs to widen its membership.

India’s PV sector is expanding at a serious pace, creating jobs and further securing energy supply for many businesses. Yet, sourcing battery cell technology at the current rate resulted in annual foreign exchange of Rs. 1012 crore creating deficits, that hopefully can be averted in the future.

The goal of the project, RE 8760 is to show how the storage of renewable energies can make them usable all year round. The generated solar power is stored and converted into hydrogen. It can also be conserved over long periods and used to recharge fuel cell vehicles during the dark winter months.

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.

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.

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.

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?

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.

Ahead of its upcoming webinar, on March 27, JinkoSolar’s Head of Technical Service Europe, Andrea Viaro, discusses the company’s new Half Cell (HC) Series, the benefits of multi-busbar and bifacial technology, and upcoming innovations, in a Q&A with pv magazine.

Vikram Solar and CEA will look to enhance research and development on high-efficiency crystalline silicon cells, modules and systems. A host of high-efficiency generation and storage technologies for French and Indian markets are also in the planning.
