Halide Perovskite Integrated Photovoltaic Cathodes Incorporating Pt on ZIF‐8‐Derived Carbon for Solar Hydrogen Production

Advanced Functional Materials, EarlyView.
A low‐Pt catalyst supported on zeolitic imidazolate framework (ZIF‐8)‐derived porous carbon and graphite is integrated with a halide perovskite photovoltaic, yielding cathodes that achieve a high photocurrent density (∼20 mA cm−2) under simulated sunlight and exhibit remarkable stability in acidic media over several days, thereby demonstrating a ...

A Naphthalimide‐Based NIR‐Emissive AIE Photosensitizer for Synergistic Apoptosis/Ferroptosis‐Mediated Antitumor Therapy and Broad‐Spectrum Bacterial Inactivation With Rapid Wound Healing

Advanced Healthcare Materials, EarlyView.
An ionic naphthalimide AIE photosensitizer (PS), TPAPV‐NIM‐M, anchors to cellular and bacterial membranes, emits in the far‐red/near‐infrared (NIR) region, and efficiently generates reactive oxygen species (ROS) under white light. Its membrane‐localized photodynamic action drives apoptosis/ferroptosis‐mediated tumor suppression and broad‐spectrum ...

Investigating the Effect of Inclination Angle of Magnetic Field Vector on Silicon PV Modules

International Journal of Photoenergy, 2021
In earlier studies, we have shown theoretically and experimentally that magnetic fields (MFs) have negative impact on silicon PV module (photovoltaic module). A noticeable decline in photocurrent with a slight increase in photovoltage was observed. Also,

Electrical Modeling of Bifacial PV Modules [PDF]

IEEE Journal of Photovoltaics
Although the bifacial photovoltaic (PV) module is now a mature technology, there still exists a gap in the literature on its electrical modeling and equivalent circuit representation. Most published studies have mainly focused on the photocurrent while overlooking other crucial parameters for the electrical response of the module.

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 ...

Temperature based maximum power point tracking for photovoltaic modules

Scientific Reports, 2020
In this article authors propose a temperature based Maximum Power Point Tracking algorithm (MPPT). Authors show that there is an optimal current vs maximum power curve that depends on photovoltaic (PV) module temperature.
