Solar panel technology is not a set-and-forget process. The technology is constantly evolving because scientists and energy researchers around the world see the future potential for solar becoming the best method for renewable energy generation.
Here’s our roundup of the best global solar panel technologies so far in 2019. Let us know on social if you’ve heard of any other new solar technologies.
The Georgia Institute of Technology is researching a way to make cheaper, flexible solar cells.
Here are the key details about the technology:
Georgia Institue of Technology’s perovskite-based solar cells are approaching the amount of energy efficiency seen in traditional silicon-based cells.
Researchers from Georgia Institute of Technology, University of California San Diego and Massachusetts Institute of Technology are involved in researching these perovskite-based solar cells.
Perovskite solar cells would be cheaper, more flexible and lighter than silicon.
Researchers have tested many different materials, and have found adding alkali metal to perovskite gives the best performance they have seen so far.
Testing has found “dead zones” in the solar cells that produce no current. Normal solar cells would normally fail if any dead zones occur, but the perovskite material was still able to function, though not at 100%.
The researchers are confident and optimistic that this technology will produce great results in the future while being cost effective.
“These materials promise to be very cost effective and high performing, which is pretty much what we need to make sure photovoltaic panels are deployed widely. We want to try to offset issues of climate change, so the idea is to have photovoltaic cells that are as cheap as possible.”
