Bridging the gap between battery and supercapacitor

By engineering the structure of a hard carbon electrode, scientists at the CIC energIGUNE research center have created an ‘ultrafast battery’ which has been shown to combine the energy density of a lithium device with the fast discharge times normally associated with supercapacitors.

‘India will add 14 GW of solar this year’

The annual global outlook report for solar published by IHS Markit notes there was no real uptick in the amount of new capacity added last year, compared with the returns seen in 2018. That is likely to kill any hope India has of overtaking the U.S. as the world’s second biggest solar market in 2020.

Maximizing the potential of PV irrigation in Spain’s ‘Sea of Plastic’

Spanish researchers have developed an analytical model to optimize the operation of PV water pumping systems. They say simultaneously irrigating different parts of a farm could help minimize costs and maximize energy use. The model was tested on an olive farm divided into four zones in the Spanish province of Almería.

The long read: PV’s Polish cold turkey

Considering the remarkable advances made by the solar sector since the Rio ‘Earth Summit’ of 1992, PV was notable by its absence at the Convention of Parties climate change summit held by the UN in Poland.

This year could see a reckoning for ultra-mega PV projects

The fate of the clutch of 500 MW-plus projects due to break ground this year could determine whether such ambitious schemes have a viable future, says Wood Mackenzie in its solar 2019 forecast. And the Indian market should brace for consolidation, add the analysts, because of aggressive reverse-auction tariff pricing.

Hyper low costs ensure clean energy investment fell in India last year

The nation still managed to attract around $11.1 billion for renewable energy in 2018, to be the world’s fifth most attractive destination for funds, according to new figures compiled by BloombergNEF.

“Optical Tweezers can benefit solar cell research” – Interview

pv magazine interviewed Ricardo Arias González, who holds a PhD in Physical Sciences and introduced the Optical Tweezers applied to biology in Spain. It is one of the tools of photonics for which Arthur Ashkin received the Nobel Prize in Physics in 2018, together with Donna Strickland and Gérard Mourou.
