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

open access: yesAdvanced 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 ...

Design description of the Schuchuli Village photovoltaic power system [PDF]

open access: yes
A stand alone photovoltaic (PV) power system for the village of Schuchuli (Gunsight), Arizona, on the Papago Indian Reservation is a limited energy, all 120 V (d.c.) system to which loads cannot be arbitrarily added and consists of a 3.5 kW (peak) PV ...

Integrated Lead/Iodine Management for Sustainable Perovskite Solar Modules

open access: yesAdvanced Materials, EarlyView.
Perovskite solar modules face environmental risks from lead and iodine leakage. A dual‐function adsorbent—porphyrin‐modified whitlockite nanocomposites—effectively captures iodine and Pb2+, even under severe damage. Combined with a semi‐closed recycling process, it recovers 96.9% high‐purity PbI2 and reduces residual Pb2+ to <10 ppb, offering an ...

Comparison between the conventional methods and PSO based MPPT algorithm for photovoltaic systems [PDF]

open access: yes, 2014
Since the output characteristics of photovoltaic (PV) system depends on the ambient temperature, solar radiation and load impedance, its maximum power point (MPP) is not constant. Under each condition PV module has a point at which it can produce its MPP.
