Technology and R&D

Scientists in the United States developed what they describe as a ‘scotch-tape like’ solution, which can absorb potential lead leakage from perovskite solar cells, preventing the toxic material from entering the environment. The tape, according to the scientists, can easily be integrated with existing encapsulation strategies, and was shown to absorb 99.9% of lead leaked from cells from that were severely damaged.

Developed by U.S. scientists, the cell is claimed to achieve an equivalent bifacial efficiency of more than 20% with an open-circuit voltage of more than 2 V. The choice of the bifacial architecture is intended at increasing the device’s power yield in order to offset the high costs for producing the CdSeTe sub-cell.

The horizontal single-axis tracker has the typical size of 195×2.5m and its tracking range is 55 degrees. The new product is an evolution of the company’s two-in-portrait solution and was conceived to meet the increasing demand for one-in-portrait trackers.

A Danish-German research team has shown that using cadmium sulfide as an n-type partner in heterojunction tandem solar cells based on selenium does not produce satisfying results. The team has discouraged other scientists from following the same path.

Australia is blessed with an incredible solar resource, but it will be diminished by global warming.

Developed by Spanish scientists, the proposed system design is said to be able to achieve water temperatures above 70 degrees Celsius and to cover around 85% of the annual sanitary hot water consumption of a household with six people.

The solar module has an area of 31.5cm² and is relying on perovskite cells with an efficiency of 22.9%. It was encapsulated with a special ionogel that is claimed to enhance the module’s impact resistivity and stability, as well as to reduce the possibility of lead leakage.

Scientists in India developed a mathematical model to predict the output of solar cells and modules in the field. The model was developed and tested using both sun simulator and actual installed modules. The scientists state that their model can be applied to a PV installation anywhere in the world, and that by taking into account module degradation over time their forecasts can be as much as 26% more accurate than existing energy yield models.

Australian startup Gelion is seeking to commercialize a non-flow zinc-bromide battery based on a stable gel replacing a flowing electrolyte. According to the manufacturer, the device is safe, robust and recyclable.

The funds should be allocated through multilateral and bilateral grants, concessional loans, guarantees and private investments. A task force will now seek to identify initial sources of financing for the electricity and coal mining sectors, as well as financing options for the development of electromobility and green hydrogen.
