Heliatek claims new conversion efficiency record for organic PV cells

German solar technology firm Heliatek claims to have outdone itself by setting a new world record for directly converting sunlight into electricity using organic photovoltaic cells. In 2012 it claimed a then world record 10.7 percent conversion efficiency and said it was gunning for 15 percent in the near future. This week it announced it's halfway there, achieving a new record of 13.2 percent.

A green process for extracting gold

A research team at the University of Saskatchewan has found what may be an inexpensive and environmentally-friendly way of recycling gold from jewelry and electronics. Using a solution of what is essentially reusable table vinegar, the team has shown that for CAD$66 (about US$47) it can produce one kilogram (2.2 lb) of gold with 100 liters (26 gal) of reusable waste water – this is as compared to current methods that can cost over CAD$1,500 (US$1,070) and create 5,000 liters (1,321 gal) of toxic, non-reusable waste.

Cheaper, longer-lasting perovskite solar cells could be on the way

Perovskite solar cells are one of the most exciting green energy technologies to emerge in recent years, combining low cost with high energy conversion rates. Now, researchers at the Swiss Federal Institute of Technology in Lausanne (EPFL) have found a way to cut their cost even further by developing a charge-carrying material that is much cheaper, highly efficient, and could even help address the technology's current major weakness by significantly lengthening the lifespan of the panels.

GE turns out the lights on CFLs

Compact fluorescent lamps (CFLs) that could fit into standard light sockets only hit the market in the 1980s, but the signs are their days may be numbered. GE has announced it will cease production of CFLs this year and instead switch its focus to producing LEDs.

Study looks at long-term impact of farming

Human use of land for crops and herds has completely altered the world's landscapes. A new field of research called experimental socio-ecology looks to the past to predict the consequences of this type of human activity in the future. Researchers at Arizona State University have spent the last 10 years studying the effects that small-scale farmers have had on land in the Mediterranean, and now they have released a report with the findings of the project.

Statistically, humanity is almost certainly responsible for global warming

The world is getting warmer, with 13 out of the 15 warmest years on record occurring in the current century. But just how sure are we that humanity's burning of oil and coal is the key factor in the temperature increase? A new project, led by researchers at the Potsdam Institute for Climate Impact Research, has answered that very question, working to estimate the likelihood of those temperature trends occurring naturally.

Plant openings signal "birth of large-scale solar in Australia"

According to the Energy Supply Association of Australia, Australia boasts the highest rate of household solar panel installation in the world. But despite much of the continent being seemingly perfect for large scale solar, it has been slow in coming to the sun-drenched country. That could be set to change with the official opening of two plants that AGL Energy managing director and CEO Andy Vesey says "signals the birth of large-scale solar in Australia".
