ABU DHABI // Masdar Institute researchers are developing a new technique to make solar absorbers more efficient at generating electricity.
Their collaboration with the Massachusetts Institute of Technology (MIT) aims to produce a solar absorber that uses tiny holes to absorb about 90 per cent of the Sun’s rays. The holes are 200 times smaller than the width of a human hair.
If successful, the technique could significantly reduce the cost of using solar power, according to the researchers.
Unlike traditional solar absorbers, the new version requires very little material and consists of only two layers – a semiconductor film and a reflective metallic layer, with a total thickness of 170 nanometres.
“This idea can be applied to most conventional solar absorbers. With this unique patterning, the absorbers can be boosted to harvest more solar energy from the ultraviolet and visible regions of the electromagnetic spectrum,” said Dr Jin You Lu, a postdoctoral researcher at Masdar Institute.
Dr Zhang Tiejun, an assistant professor of mechanical and materials engineering at Masdar Institute, said the research team had developed a simple and cost-effective fabrication technique.
Dr Zhang and researchers from MIT recently co-authored an article on the new technique that could lead to lower carbon emissions resulting from the use of electrical appliances.
Dr Nicholas Fang Xuanlai, professor of mechanical engineering at MIT and co-principal investigator on the project, said the collaboration had led to new insights in the emerging field of plasmonics, the study of how an electromagnetic field and free electrons in a metal interact.
Trapping sunlight in plasmonics could allow the solar absorber to better trap and disperse energy, he said.
“We look forward to testing the overall solar conversion efficiency of the coating materials in the next step of our research,” said Dr Fang.

Mercer, the investment consulting arm of US services company Marsh & McLennan, expects its wealth division to at least double its assets under management (AUM) in the Middle East as wealth in the region continues to grow despite economic headwinds, a company official said.
Mercer Wealth, which globally has $160 billion in AUM, plans to boost its AUM in the region to $2-$3bn in the next 2-3 years from the present $1bn, said Yasir AbuShaban, a Dubai-based principal with Mercer Wealth.
“Within the next two to three years, we are looking at reaching $2 to $3 billion as a conservative estimate and we do see an opportunity to do so,” said Mr AbuShaban.
Mercer does not directly make investments, but allocates clients’ money they have discretion to, to professional asset managers. They also provide advice to clients.
“We have buying power. We can negotiate on their (client’s) behalf with asset managers to provide them lower fees than they otherwise would have to get on their own,” he added.
Mercer Wealth’s clients include sovereign wealth funds, family offices, and insurance companies among others.
From its office in Dubai, Mercer also looks after Africa, India and Turkey, where they also see opportunity for growth.
Wealth creation in Middle East and Africa (MEA) grew 8.5 per cent to $8.1 trillion last year from $7.5tn in 2015, higher than last year’s global average of 6 per cent and the second-highest growth in a region after Asia-Pacific which grew 9.9 per cent, according to consultancy Boston Consulting Group (BCG). In the region, where wealth grew just 1.9 per cent in 2015 compared with 2014, a pickup in oil prices has helped in wealth generation.
BCG is forecasting MEA wealth will rise to $12tn by 2021, growing at an annual average of 8 per cent.
Drivers of wealth generation in the region will be split evenly between new wealth creation and growth of performance of existing assets, according to BCG.
Another general trend in the region is clients’ looking for a comprehensive approach to investing, according to Mr AbuShaban.
“Institutional investors or some of the families are seeing a slowdown in the available capital they have to invest and in that sense they are looking at optimizing the way they manage their portfolios and making sure they are not investing haphazardly and different parts of their investment are working together,” said Mr AbuShaban.
Some clients also have a higher appetite for risk, given the low interest-rate environment that does not provide enough yield for some institutional investors. These clients are keen to invest in illiquid assets, such as private equity and infrastructure.
“What we have seen is a desire for higher returns in what has been a low-return environment specifically in various fixed income or bonds,” he said.
“In this environment, we have seen a de facto increase in the risk that clients are taking in things like illiquid investments, private equity investments, infrastructure and private debt, those kind of investments were higher illiquidity results in incrementally higher returns.”
The Abu Dhabi Investment Authority, one of the largest sovereign wealth funds, said in its 2016 report that has gradually increased its exposure in direct private equity and private credit transactions, mainly in Asian markets and especially in China and India. The authority’s private equity department focused on structured equities owing to “their defensive characteristics.”

Kat Wightman's tips on how to create zones in large spaces
- Area carpets or rugs are the easiest way to segregate spaces while also unifying them.
- Lighting can help define areas. Try pendant lighting over dining tables, and side and floor lamps in living areas.
- Keep the colour palette the same in a room, but combine different tones and textures in different zone. A common accent colour dotted throughout the space brings it together.
- Don’t be afraid to use furniture to break up the space. For example, if you have a sofa placed in the middle of the room, a console unit behind it will give good punctuation.
- Use a considered collection of prints and artworks that work together to form a cohesive journey.
