Ultra-thin 2D perovskite solar cell with 18.3% efficiency

The solar cell was built with a layer of organic cations between the iodide on top, and lead on the bottom enhanced interactions between the layers. Its creators designed the device after they discovered that, when the sunlight hits a 2D perovskite, it contracts the space between atomic layers in the material.

The Hydrogen Stream: A fuel cell gigafactory in the US and new plans from Australia

U.S. hydrogen solutions company Plug Power opened, this week, its green hydrogen and fuel cell gigafactory in New York state. In Australia, Patriot Energy announced a supply agreement for 75 modular green hydrogen generation units, and ARENA said it will play a key role in the development and delivery of the German-Australian Hydrogen Innovation and Technology Incubator.

Detergent for solar module cleaning and protection

Developed and distributed by Portuguese start-up ChemiTek, the detergent is claimed to reduce water consumption by about 50% and increase energy production by up to 5%. The product was recently certified by the German laboratory TÜV Sud, according to the EN 61215 standard.

Simulation tool to measure effect of waves on offshore floating solar

Developed by scientists in Malta, the tool is said to predict yield gains or losses that waves can determine in offshore PV installations. The research group identified three movements an offshore array can be subject to, and for each of them provided specific measurements.

Australia removes much-criticized DC isolator mandate

Following years of lobbying, the Standards Australia Committee has removed the requirement for rooftop solar installations to include a DC isolator.
