slim, adaptable solar panels might soon drape and energize your belongings
Good day, folks! Let's chat about some exciting, groundbreaking tech that's about to revolutionize our world – ultra-thin, flexible solar panels! Thanks to Oxford University's whiz-kid physicists, we're edging closer to tech that could power all your devices, from your home to your phone, without the cumbersome, conventional solar panels.
This innovation hinges on a nifty technique allowing for multiple layers of light-absorbing material to be tightly packed into an ultra-thin solar cell, thinner than some bacteria! You heard that right – it's just a single micron thick, versus conventional solar panels that are a whopping 150 times thicker. This ultra-thin design enables the cells to be utilized as a coating, providing much-needed flexibility without sacrificing efficiency.
The team is set to publish a paper detailing the methods for creating these marvels of engineering later this year in an academic journal. The tech has already garnered a stamp of approval from Japan's National Institute of Advanced Industrial Science and Technology, verifying they convert a whopping 27% of sunlight into electricity. That's a crucial number since it matches – or even exceeds – the average efficiency of traditional solar panel materials.
Shuaifeng Hu, a post-doctoral fellow at Oxford, shared his enthusiasm, "We've raised power conversion efficiency from around 6% to over 27% in just five years by experimenting with our stacking or multi-junction approach. We believe that, over time, this approach could enable photovoltaic devices to achieve far greater efficiencies, exceeding 45%."
Some researchers behind this tech have even begun commercial ventures, like Oxford PV, a brainchild of Henry Snaith, a professor at Oxford who spearheaded the school's work in photovoltaics. They've already commenced large-scale manufacturing operations.
While we typically picture gigantic solar farms when we think of solar energy, the hope is that perovskite cells can bring renewable energy directly to our homes, vehicles, and even clothing. Researchers have been working tirelessly to make solar power a more feasible option, exploring even wilder ideas like creating electricity from water and light. They've been successful – the price of solar power has plummeted by over 80% since 2010!
Junke Wang, another postdoctoral fellow at Oxford, envisions a future where perovskite coatings can generate cheap solar power on broader surfaces, such as car and building roofs, as well as the backs of mobile phones. If more solar energy can be generated in this way, we could see less need in the longer term to use the traditional silicon panels or build countless solar farms.
With CO2 emissions need to drop drastically, and soon, to avert a climate disaster, the prospect of shiny, power-generating backpacks can't come fast enough! Stay tuned for more updates on this game-changing technology.
