Spiro‐Phenothiazine Hole‐Transporting Materials: Unlocking Stability and Scalability in Perovskite Solar Cells

Advanced Materials, EarlyView.
Fluorene‐functionalized spiro‐phenothiazine (PTZ‐Fl) exhibits strong Li+ affinity and thermal stability, enabling a PCE of 25.75% in small‐area cells and 22.07% in 25 cm2 modules. Under ISOS‐L3 conditions, PTZ‐Flbased devices retain over 80% efficiency after 1000 hours, demonstrating superior stability and scalability compared to spiro‐OMeTAD for next ...

Solar Tracking Systems – A Review

Journal of Mines, Metals and Fuels, 2023
The biggest challenge and concern for the upcoming 50 years is the idea of power generation, by making less use of the fossil fuels. The idea of solar energy as fuel, and the fact that we can convert freely available energy which we receive from the sun into usable energy, is fascinating, and is probably at the highest priority at the moment as ...
