DOI: 10.1002/adfm.202423635 A team of materials scientists and solar engineers at Nanyang Technological University in Singapore, working with a colleague from Polytechnique Hauts-de-France, has developed a perovskite solar cell using a biomass-based polymer. In their paper published in the journal Advanced Functional Materials, the group describes how they used agricultural waste to make the photoactive layer of the cell, and in so doing, found that ...
