This projected increase of people living in extreme poverty is very worrisome. The largest part is projected for sub-Saharan Africa, where there is also the highest number of people without access to electricity. Photovoltaics could help to turn this trajectory around.
In the last decades, the world has made fantastic progress against extreme poverty. In 1990, 2.3 billion people lived in extreme poverty. Since then, the number of extremely poor people has declined by 1.5 *billion* people. 🧵

If true, this would be quite an achievement. Does anyone knows any more detail about which technology is used? As the thickness is specified to be in the micrometer range I guess not perovskites but maybe something based on III-V semiconductors ??
