A new report states New Zealand is already well on the way to reaching its ambitious goal of 90 percent renewable energy by 2025. However, more needs to be done to reduce heavy emissions of greenhouse gases (GHG) from the island nation.
Commissioned by the Royal Society of New Zealand, the report was written by a panel of climate experts led by Victoria University Professor Ralph Sims.
While perovskite solar cells can offer an efficiency similar to silicon at a lower cost, they have less thermal stability. Brown University-led research may have addressed this challenge.
A converted form of perovskite, called formamidinium lead triiodide (FAPbI3), has better thermal stability and light absorption attributes. It’s been around for a while; but up until now has been quite difficult to manufacture.
Most aquatic solar installations have been placed on relatively calm bodies of water to date as rough seas can destroy solar equipment and the platforms on which they are installed.
However, a new development from the Vienna University of Technology may enable oceanic solar farms to be established.
The TU Wien invention is a platform system that can span one hundred metres long while remaining steady during rough weather.
25 countries participating in the International Solar Alliance (ISA) have pledged to take action that could unleash investment of up to USD $1 trillion in solar energy assets.
The announcement was made at an event in New York late last week. Among the countries participating in the action are India, the USA and France.
