According to the Gold Member Solar Report by EnergyTrend (Q3 2018), monocrystalline module prices have fallen almost 20% this year, while those for polycrystalline modules have dropped by more than 25%. Increased consolidation among manufacturers and developers is expected to occur in China and the global solar market, with more merger deals, plans for capacity reductions and even factory closures.

The Intergovernmental Panel on Climate Change (IPCC) has released a new report on different ways global warming can be kept within the 1.5°C limit. The panel seeks to inform policymakers before the upcoming COP24 in Poland this December. Resulting from their analysis, the 91 authors state that drastic action and significant investments are needed. Such climate action across all sectors would have significant positive effects on sustainable development progress, they say.

TOPCon technologies could further increase solar cell efficiencies, said Guangyao Jin, chief scientist, DuPont Photovoltaic Solutions, at this year’s Energy Taiwan, held in September. He added that metallization paste is crucial.

Solar power plants not only need to be built, but also operated, monitored, and maintained. Many approaches to digitalization promise to make these plant management processes significantly more efficient – up to a factor of 10.

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.

In another ambitious announcement, SoftBank Group CEO, Masayoshi Son has said he will give free power from solar power projects after 25 years of PPA to all ISA member countries. He was speaking at the Indian Government organized RE Invest 2018.

A new report published by business consultants Frost & Sullivan expects around 90 GW of new solar installations by the end of 2018, in line with the predictions of other leading analysts. It further notes that PV remains the world leader in renewable energy capacity, and that markets are moving away from feed-in tariffs to make increasing use of auction models and private PPAs.

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.

As backsheet manufacturers aim to keep up with cost reductions up and down the PV supply chain, new processes and materials are appearing, with claims to offer better performance as a moisture barrier, as well as better acetic acid permeability and higher reflectivity, among other features. pv magazine examines the state of the market for PV backsheets, and takes a look at some of the new material innovations that are gaining ground with module manufacturers.

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.
