How Can the Micro-Grid Solar Solution Realize Electrification in Regions Without Power Supply?

The electrification revolution, which began in the 1860’s, completely changed the way people live and promoted social development. But according to the World Bank's State of Electricity Access Report there are 1.06 billion powerless people around the world. They still live in the dark and do not enjoy the benefits of electrification. 87% of them live in remote rural areas and islands far from power grids. Unfortunately, the cost to extend the power grid to them is too high. … read more

Small Modular Reactors: Launching in 2018

Small modular reactors (SMRs) are an innovation on nuclear plant design that could replace coal-fired steam turbines with zero or near-zero carbon emissions.  While there are approximately 50 SMR designs around the world, only NuScale, an SMR-startup based in Portland, Oregon, has sought US licensing.   NuScale cleared stage one of the US Nuclear Regulatory […]

Insight into loss processes in perovskite solar cells enables efficiency improvements

In perovskite solar cells, charge carriers are mainly lost through recombination occurring at interface defect sites. In contrast, recombination at defect sites within the perovskite layer does not limit the performance of the solar cells at present. Teams from the University of Potsdam and the Helmholtz-Zentrum Berlin (HZB) were able to reach this interesting conclusion through extremely accurate quantitative measurements on 1 cm2 perovskite cells using photoluminescence. … read more

Silicon-based, tandem photovoltaic modules can compete in solar market

The dominant existing solar technology -- silicon -- is more than 90 percent of the way to its theoretical efficiency limit. More efficient technologies will be more expensive. New research identifies the efficiency vs. cost target. … read more

Political Climate Change and the Path to Clean Energy

Could a change in the US political climate spark rapid growth in renewable energy? A group of progressive Democratic candidates believe that it can and voters are listening. Alexandria Ocasio-Cortez, a 28-year-old New York Bartender turned Bernie Sanders campaign organizer, achieved a stunning political upset last month when she beat incumbent 10-term Congressman Joe Crowley […]

Technique to easily fabricate ceramic films used as OPV inter-layers developed

Researchers developed a technique for coating Zinc related oxide (ZnOx, ZnOHx) simply by depositing the films in a solution process using the Metal Organic Decomposition method at ambient temperature and pressure without heating. They also demonstrated that their thin films produced by this technique were useful as buffer layers for OPV cells and that the films achieved a power conversion efficiency equivalent to that of ZnO thin films produced by conventional methods involving sintering. … read more

Europe may thrive on renewable energy despite unpredictable weather

Researchers have shown how long-term weather patterns affect wind and solar renewable energy technologies across Europe. The work suggests that despite the unpredictable nature of wind and solar energy, the European power system can comfortably generate at least 35 percent of its electricity using these renewables alone without major impacts on prices or system stability. … read more
