A new integrated solar battery based on carbon nitride photoanodes

https://techxplore.com/news/2023-03-solar-battery-based-carbon-nitride.html

"earth-abundant and cheap 2D polymeric carbon nitrides... one photogenerated charge carrier transferred from photoactive to counter electrode, internally, via multifunctional separator separating two electrodes...  K-PHI anode absorbs light (photogenerated electrons), while photogenerated holes transferred to cathode, made of organic conductive polymer PEDOT:PSS... increased extracted energy 94.1% compared in the dark conventional batteries... translucent nature of device may enable use in windows"
