Technology

Perovskites and quantum dot solar cells both have potential for use in high efficiency PV devices, but have major challenges to overcome to be a commercial reality. Scientists at the University of Toronto have found that if the two technologies are combined in the right way, they can stabilize each other.

While preparing for the country’s first, 1.35 GW solar tender in June, state secretary for energy João Galamba has revealed another procurement exercise will be held in January and rejected criticism next month’s auction has been badly designed.

The Institute for Energy Economics and Financial Analysis has estimated the effect on the payback period of PV systems when adding EVs and storage in Germany and Britain. In both cases, system owners are likely to reduce their payback period by significant margins as increased self-consumption can offset the incremental phase out of government incentives.

What was originally a landmark bill to establish rights for the owners of PV systems has made it to the floor of the California Senate in a dramatically reduced form.

Long awaited – and even longer debated – the 1000 pages of legislation have finally been adopted by all EU institutions. Over the coming 18 months, there will be changes, some big, some small, to the markets in Europe. Across the continent, the renewable energy industry is likely to benefit.

Researchers at the University of California, San Diego – with the help of the university’s Comet supercomputer – modelled thousands of halide compounds to come up with a shortlist of 13 materials that could be candidates for the efficient solar cell materials of the future.

The solar-plus-storage combination is super-charging the deployment of batteries across the country and IHS Markit says the U.S. will become the largest market for grid-tied energy storage this year.

Doping perovksite solar cells with potassium is said to eliminate interface trapping defects and mobile ion migration. ‘Hysteresis suppression’ is key for more efficient cells based on the promising material.

The country’s PV market has heated up, a fact reflected by the number of applications submitted to the energy regulator seeking a license to generate electricity.

Europe’s most important scientific research institutes have joined forces to make perovskite solar applications more than just a dream. The European Perovskite Initiative consortium is planning to draw up a perovskite white paper.
