New Solar Cell Method will further reduce construction emissions

New Solar Cell Method will further reduce construction emissions

Solar cells represent our best hope for capturing energy at its original source: the sun. All our energy comes from there, either directly or indirectly or very indirectly. But even making them creates some carbon dioxide emissions. The two main types are silicon (Si-PV), used in most existing installations, and perovskite, not widely used yet. This new process for injecting perovskite into inert sealed chambers gives them longer life by avoiding oxygen contact (which causes, you may guess, oxidation). Read more on inverse.com, ignoring the clickbait title and read the original Joule paper here.

Note that when the article compares SiPV’s carbon footprint when growing solar’s adoption, it seems to fail to account for the reduction in emissions from displaced coal plants.

A great place to keep up with progress on perovskite cells is PV Magazine’s web site.

Of course this all might be moot someday, if this device that generates moisture out of semi-thin air (the air must have moisture content) becomes practical.
