Flexible real-time skin dosimeter based on a thin-film copper indium gallium selenide solar cell for electron radiation therapy.

Purpose in electron radiotherapy Several dosimeters have been tested for skin dosimetry. Methods The CIGS solar cell dosimeter was comprised of a custom thin-film CIGS solar cell and a data acquisition device. A voltage amplifier with a gain of 1000, a voltage input module, a DAQ chassis, and an in-house firmware were included in the DAQ system. We measured the skin point doses by attaching the CIGS solar cell to an anthropomorphic phantom surface in order to determine clinical sensitivity. Results as the standardized signals of the solar cell dosimeter increased linearly as the delivery dose increased. Even at low doses, the solar cell dosimeter's sampling rates showed good results. The solar cell dosimeter demonstrated dose rate independence within 1% and energy independence within 3% error margins, with maximum stability within 3%. Regardless of the solar cell's rotation angle, the solar cell's results were similar when penetrating the same side of the CIGS cell. The solar cell dosimeter's measurement factor was similar to that measured by the ion chamber. The solar cell signals were similar between the baseline and the last time point at the same time. We present the design of a flexible skin dosimeter based on a CIGS solar cell. Our findings show that the CIGS solar cell has the ability to be a novel thin skin dosimeter for electron radiotherapy.

Electroactive CTAB/PVDF composite film based photo-rechargeable hybrid power cell for clean energy generation and storage.

By doping CTAB in the PVDF matrix by solution casting process, the first high dielectric polymer film was created. The basic design of this hybrid power cell has been used as a solar light absorber and photo-electron generator, while PVA-MnO 2 -Eosin Y's high dielectric CTAB/PVDF has been used as a dielectric separator cum storage component in a very cost effective manner. [Formula: see text] 5. 5 W/m 2 respectively. The hybrid cell's high storage capacity is investigated due to its high conversion rate [Formula: see text] with energy density and power density [Formula: see text] 5. 5 W/m 2 respectively.

Flow cell for operando X-ray photon-in-photon-out studies on photo-electrochemical thin film devices

The well-defined measurement system for PEC cells provides a well-defined measurement system, but it places numerous limitations on performing operando XAS experiments. Methods: : Methods: To maximize signal detection, we manufactured a novel operando photo-electro-chemical cell by computer numerical control milling, aided by the materials'u201 X-u2016 X u2011ray and visible light absorption properties to improve signal detection. Results: We demonstrate the cell's ability to measure and control X-u2019ray signals unperturbed by bubbles and to fluently exchange different thin film samples by gathering high-resolution Fe K-edge spectra during water oxidation. : Our cell designs a measurement scheme that will bring photo-electro-chemical operando HERFD-XAS experiments to a larger scientific audience, particularly because of the ease of sample exchange.
