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 Indian Ministry of New and Renewable Energy (MNRE) says the nation will exceed 175 GW of installed renewable energy capacity as plans for bidding for 115 GW of renewable power projects to March 2020 were announced. The target for PV parks has been increased from 20 GW to 40 GW with some 41 parks in 21 states – with aggregate capacity of more than 26 GW – already sanctioned.

India has unveiled a national wind-solar hybrid policy that provides a framework for promotion of large grid connected wind-solar PV systems for optimal and efficient utilization of transmission infrastructure and land, reducing the variability in renewable power generation and thus achieving better grid stability.

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.

U.S. technology company Microlink Devices has achieved a record efficiency of 37.75% on its triple junction thin film cells. The lightweight cell achieves a power density of more than 3000 W/kg, and is designed for use in satellites and unmanned air vehicles (UAVs). The new efficiency record is confirmed by the National Renewable Energy Laboratory.

The researchers found that printed solar cells achieved a better performance when they used an active polymer material as glue.

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 at European solar research organization, Solliance have announced the achievement of 14.5% conversion efficiency on a perovskite module. The module uses a glass substrate, and the efficiency was measured on an aperture area of 144 cm².

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.

Together with Austrian equipment manufacturer EVG, Fraunhofer ISE has achieved an efficiency of 33.3% on a multi-junction solar cell. The highlight of the cell is the ultra-thin II-V semiconductor layer. However, it will be a few years before mass production is possible.
