A team of scientists at University of California, Riverside investigating the ‘unusual’ electronic behavior of pristine graphene has found that, in certain configurations, the material can generate a current without the need for a p-n junction, leading to the possibility of extremely thin, lightweight solar devices.

Swiss equipment supplier Meyer Burger has received a CHF 74 million (US$74.4 million) order for a 600 MW production line combining heterojunction and smart wire technologies. The order was placed by an unnamed manufacturer, with the line expected to begin cell and module production in the second half of 2019.

The European Bank for Reconstruction and Development yesterday unveiled its new energy sector strategy, which aims to ramp up renewables investment, while moving away from coal and oil. Gas will still remain a focus, however. It has also announced this week, plans for a €250 million green bond framework, through which it hopes to double the issuance of green/sustainability bonds in its active regions; and mobilize €1 billion in private sector investment over the next three years.

Mercedes Benz has announced plans for all of its German factories to be supplied with CO2 free energy by 2022. Meanwhile, Renewables investment firm Octopus Energy has signed a five-year PPA with Shell Energy Europe to provide the global energy giant with power from several unsubsidized PV projects it is constructing in Italy.

The U.K. Solar Trade Association has published a new assessment, finding that the cost of generating solar electricity in the British Isles has already fallen far below its earlier predictions, and could reach GBP 40 (US$50)/MWh by 2030.

Scientists at Harvard University have developed a type of material that can be programmed to move in response to various stimuli, including light. One possible application, says the group, could be in solar panels with integrated microstructures that track the sun without any energy input.

Chinese solar manufacturer Seraphim has announced plans for a 500 MW cell factory in Port Elizabeth, South Africa. The company also plans to expand an existing 300 MW module factory in South Africa’s Eastern Cape region by 200 MW.

Researchers in Spain have proposed a new standard for solar cell testing, which they say could enable more accurate determinations of a cell’s annual energy yield. Using machine learning, the method processes data sets consisting of thousands of solar spectra, creating representative examples which can then be used to predict average annual efficiency.

A project backed by the European Union’s Horizon 2020 program says it has developed a self-cleaning coating for modules which is also anti reflective and weather resistant. The project – SolarSharc – expects to launch the product next year.

A new report from U.S. based Rocky Mountain Institute outlines the potential for minigrid deployment to provide electricity to underserved communities around the world, to the benefit of utility companies, minigrid developers and communities. The report takes examples from Nigeria to illustrate this potential, but states that many of its findings could be applied to communities with limited or no access to electricity around the world.
