Technology and R&D

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.

In an interview with pv magazine, vice president of GoodWe, Ron Shen, talks about the company’s plans for Germany, Spain, Africa and India, in addition to its goal to triple production capacity to 15 GW in China. He also discusses the effect of China’s 31/5 policy change, and plans for an initial public offering (IPO).

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.

The algorithm is said to be able to examine the relationship between weather forecast data and the projection of electric circuit parameters. Through this innovation, Purdue University researchers claim they can interpret the routinely collected maximum power point (MPP) time-series data, to assess the time-dependent “health” of installed solar modules.

Researchers from the University of California, Los Angeles, have set a new record 22.4% conversion efficiency for a tandem cell combining a lead-based perovskite layer with CIGS technology. The record has been confirmed by the U.S. National Renewable Energy Laboratory.
