Research & Development

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.

India’s Prime Minister kick started the first Assembly of the ISA, the second IORA Renewable Energy Ministerial Meeting, and the 2nd Global RE-Invest yesterday in Greater Noida. The agenda of the day? Universal access to solar energy at affordable rates; securing 40% of India’s electricity generation from non-fossil fuels by 2030, and allocating up to US$80 billion to boost domestic PV manufacturing.

A team of researchers from the Okinawa Institute of Science and Technology (OIST) has developed a new process for the production of perovskite solar devices; and reports a 5x5cm² device with an efficiency above 15%. The researchers worked with a 1 micron thick active layer, considerably thicker than in many other perovskite devices, and state that this helped achieve better long-term stability.

Although the “solar flow battery” is currently considered too expensive by its own creators, a further improvement of its design and the use of emerging solar materials and new electrochemistry may open new opportunities for this kind of technology.

This means that this promising material, contrary to common belief, is able to form domains of polarized strain to minimize elastic energy. The research team made its discovery by using multimodal imaging.

The Belgian research institute developed its cell in partnership with EnergyVille, Solliance and German research center, ZSW.

pv magazine’s Future PV Roundtable, held at the 2018 Renewable Energy India (REI) Expo in Greater Noida, discussed how India can better adopt bifacial solar cell and module technology – the future of power generation. Prominent industry speakers also put forth their views on how standards can catalyze solar innovation for India-specific challenges, and on PV materials and components for enhanced module efficiency and recycling.

By adopting resource efficiency measures, the Indian PV solar manufacturing sector can reduce its material requirement from an estimated 12 million tons to 8.2 million tons by 2030. The resource-efficient approach will also increase efficiency to more than 30% from 6% in 2018, according to a study conducted under the European Union’s Resource Efficiency Initiative (EU-REI) Project.

The benefits of deploying bifacial solar panels on single-axis trackers are touted like snake oil these days, with promises of anywhere from 5 to 50% gains in energy output compared with a monofacial panel. Unfortunately, the field data that might delineate the actual energy gain of a bifacial panel on a tracker are hard to acquire, and the data that are available typically describe small-scale tests under tightly defined conditions.

Following hot on the heels of Exide Industries, lead acid battery maker, Indian-based Amara Raja Batteries Limited has said it will set up a 100 MWh lithium ion assembly plant in Andhra Pradesh. The company aims to establish a foothold in the energy storage market for electric vehicles.
