Hello fellow solar enthusiasts,
The solar industry is a rapidly evolving sphere of ever-expanding possibilities and it never ceases to amaze me how far we’ve come. Today, I’d like to take a moment to delve into the depths of perovskite solar cells, which are a fascinating area within our realm that is worth exploring.
Scientific advancements of late are showing particularly exciting potential. Recently, US research scientists at Rice University in Houston, Texas, have uncovered an effective way to enhance the stability of perovskite solar cells. Their method involves utilizing a “seasoning” technique with two-dimensional (2D) perovskites.
For the uninitiated, formamidinium lead iodide is a chemical used in high-efficiency perovskite solar cells. The researchers hypothesized if this solution could be tempered using more stable 2D perovskites as a template, this might confer superior stability during growth.
To test this theory, the researchers fabricated four types of 2D perovskites, with half closely matching the surface structure of formamidinium lead iodide. The findings were much as expected! The solar cells which incorporated the well-matched 2D perovskite template showed not only improved efficiency but also increased durability. How remarkable, isn’t it?
In the grand scheme of solar, what does this mean for solar companies or homeowners considering solar panels for your home? Simply put, a solar array for home that utilizes perovskite solar cells could potentially offer greater durability and efficiency over a longer time-frame – a win-win when considering a solar investment.
The real game-changer, however, is that the 2D template solar cells that had an added encapsulation layer showed unprecedented stability, of the sort that begins to approach commercial relevance. What’s even more impressive is that these solar cells maintained almost their full efficiency up to 85 C…for a whopping 1,000 hours!
These improved perovskite solar cells not only enhance light-harvesting capabilities but could also be the key to lowering manufacturing costs for solar companies. This could mean making solar power more affordable and accessible to a wider range of homeowners.
The versatility of perovskites doesn’t stop there though. These solar cells can be created on a variety of substrates, including plastic, which opens up possibilities for more flexible and lightweight solar panels. This could quite literally reshape the way we perceive solar arrays for homes.
This is certainly a development to keep an eye on, as it signals a shift in the solar industry that could spark a revolution in how we produce and consume solar power. I look forward to watching as this unfolds and continuing to update you on the latest breakthroughs within the industry.
Stay tuned and keep chasing the sunlight,
