Technology and R&D

A technique based on optical imaging has been used by an international research team to illuminate strains in lead halide perovskite solar cells without harming them. The scientists claim the approach helped them discover misorientation between microscopic perovskite crystals was the main cause of the strains.

A team of scientists led by the University of Glasgow has discovered a more efficient method of splitting water into hydrogen and oxygen using electricity which it says could almost double the amount of hydrogen produced per millivolt.

The government of the Philippines will spend $500 million on solar-powered water supply and desalination in remote areas of Mindanao, the second-largest island in the archipelago. Elsewhere, a Finnish study has suggested drought-hit Iran could benefit from renewable-powered desalination.

A U.S. research team has used protein bacteriorhodopsin to improve the efficiency of what it called ‘bioperovskite’ solar cells. The scientists used Förster Resonance Energy Transfer to predict the strength of long-range excitonic transport between the perovskite and protein layers.

Research from the United States has demonstrated how PV technology can be used to kill cancer cells. Although still at an embryonic stage, the findings of the study and initial test results suggest solar power could be an effective tool in relation to light-activated fluorescent dyes for disease diagnosis, image-guided surgery and site-specific tumor treatment.

Although PV trails wind and nuclear in terms of its anticipated future footprint, the opposition party’s attempt to outflank left of center rivals on climate change has resulted in one of the world’s most ambitious national roadmaps towards a zero-carbon future.

The four-year-old Hangzhou-based business says it already has a 20 MW perovskite module pilot line and is working on a mass production facility in the city of Quzhou.

A study has estimated the cost of PV project soiling may increase from €3-5 billion last year to €4-7 billion by 2023 due to more extensive deployment in high insolation and soiling-affected regions, such as China and India. The authors of the paper outlined the potential of soiling mitigation technologies while stressing more R&D is needed to reduce costs and for the adoption of such measures on a larger scale.

A German start-up achieved more than 99% efficiency when charging a vehicle developed by the Bochum University of Applied Sciences with electricity from solar cells. Ambibox’s DC charging technology was used in a research project in the Australian desert.

Scientists at the Tokyo Institute of Technology have developed a carbon nanotube which forms a strong junction with a lead-halide perovskite, improving performance and stability.
