Solar Technology & PV R&D News

With the 200 hydrogen bikes offered to journalists and world leaders at the G7 summit in Biarritz proving popular, manufacturer Pragma Industries has received an order for 1,000 of them from Chilean president Sebastian Pinera. The company’s founder, Pierre Forté, wants the bike to have a societal impact in developing countries.

Scientists at the institution have achieved 21.6% efficiency with a perovskite cell measuring 1cm². The landmark has been verified as a new world record for perovskites at this size.

Another study has highlighted the advantages of combining solar with agriculture. According to the paper, growing chiltepin pepper, jalapeno and cherry tomato in dryland areas of the U.S. under the shade of PV modules is not only possible, but can lead to a better harvest.

A new coating developed by scientists at Stanford promises to bring lithium metal batteries ‘closer to reality’, by significantly extending their operational lifetime and limiting the occurrence of dendrites at the anode, which can cause short circuiting and fires.

The levelized cost of energy produced by large scale PV projects ranges from €24/MWh in southern Spain to €42/MWh in Finland. New research states that is already cheaper than the average spot market electricity price and that the figure for big facilities in southern Spain may fall to €14 in 2030 and €9 in 2050.

Mathematicians at Canada’s University of Waterloo who turned their attention to solar power have developed an algorithm they say offers better control over PV plant output. The researchers estimate the algorithm could improve the output of a 100 MW power plant by almost a million kilowatt-hours per year.

An international team of researchers led by the University of Tokyo has discovered a new material which, when rolled into a nanotube, generates an electric current if exposed to light. If magnified and scaled up, say the scientists, the technology could be used in future high-efficiency solar devices.

Scientists at the Royal Melbourne Institute of Technology have developed a method for producing a ‘smart fabric’ with a supercapacitor energy storage device embedded in it. Its developers say it can be readily integrated with a solar cell or used to power wearable technology.

A European consortium of partners has developed an easy-to-clean solar panel coating that repels environmental forces. SolarSharc was created by the Advanced Resins and Coatings Innovation Centre (a strategic partnership between London South Bank University and TWI), Opus Materials Technologies, Onyx Solar, CEA – LITEN, Millidyne and TWI.

X-ray analysis is said to have solved the mystery of how to preserve optical absorption in perovskite layers. Researchers say the discovery could help stabilize the material and speed up the launch of a new ingredient for PV research.

The improved performance was achieved by using a methylene bridged material, the molecular dye DfZnP-iPr.

Traditional solar cookers concentrate sunlight on mirrored surfaces and convert it into heat. But this summer, Sunspot unveiled Sunspot Solar Electric Cooking, a new cooker based on PV technology. The system relies on two PV modules, a lead-carbon battery, an inverter, and an induction cooktop.

MIT researchers say climate change could reduce the yield of solar modules. Analysis based on the warming scenarios outlined by the IPCC predicts in some areas the annual energy output of PV systems may fall by up to 50 kWh per kilowatt installed.

A research team from Columbia University has designed organic molecules that can produce excitons with a longer lifecycle than inorganic equivalents. The excitons have the potential to amplify the amount of electricity generated by the photons a solar cell absorbs.

A new method of creating an ordered mesh of nanowires, developed by scientists at the Lawrence Livermore National Laboratory in the United States, could lead to the creation of more efficient transparent electrode layers in solar cells – and the elimination of a rare material from the manufacturing process.
