Perovskite solar cells, a promising alternative to traditional silicon-based panels, have been plagued by durability issues. However, recent breakthroughs could change that. Researchers at Northwestern University, Griffith University, and the University of Toronto have discovered a way to improve perovskite stability threefold.
The new coating, made from amidinium, has been shown to resist decomposition 10 times better than conventional ammonium-based coatings. This means that perovskite solar cells could now last for up to two decades, making them more viable for commercial use.
The advantages of perovskite solar cells include their low cost and flexibility. They can be produced at room temperature, which reduces production costs compared to silicon-based panels. Additionally, perovskites can absorb a larger portion of sunlight, leading to higher theoretical efficiency.
However, potential leakage of heavy metals is still a concern. Silicon-perovskite tandem cells are also an option instead of solely perovskite systems.
To address durability issues, the researchers used amidinium, a nitrogen-based compound that improves the protective layers on top of the perovskite cells. This approach has been successful in boosting the overall durability of solar panels.
First Solar, Inc., the largest solar panel manufacturer in the USA and Western hemisphere, is also investing in perovskite technology. The company aims to ramp up its production capacity quickly and could benefit from tariffs on Chinese imports.
With growing demand for solar energy, investments in solar companies can provide a promising return. Several ETFs, such as Global X Solar ETF (RAYS) and Invesco Solar ETF (TAN), offer diversified exposure to the industry.
