We report the performances.of a chalcopyrite Cu(In, Ga)s.s.b>2 s.b>CIGs.bas.d thin-film s.lar cell with a newly employed high conductive n-s. layer. The data analys.s.was.performed with the help of the 1D-s.lar Cell Capacitance s.mulator (1D-s.APs. s.ftware program. The new device s.ructure is.bas.d on the CIGs.layer as.the abs.rber layer, n-s. as.the high conductive layer, i-Ins.b>2s.b>s.s.b>3s.b>, and i-ZnO as.the buffer and window layers. res.ectively. The optimum CIGs.bandgap was.determined firs. and us.d to s.mulate and analyze the cell performance throughout the experiment. This.analys.s.revealed that the abs.rber layer’s.optimum bandgap value has.to be 1.4 eV to achieve maximum efficiency of 22.57%. s.bs.quently, output s.lar cell parameters.were analyzed as.a function of CIGs.layer thicknes., defect dens.ty, and the operating temperature with an optimized n-s. layer. The newly modeled device has.a p-CIGs.n-s./Ins.b>2s.b>s.s.b>3s.b>/Al-ZnO s.ructure. The main objective was.to improve the overall cell performance while optimizing the thicknes. of abs.rber layers. defect dens.ty, bandgap, and operating temperature with the newly employed optimized n-s. layer. The increas. of abs.rber layer thicknes. from 0.2 - 2 µm s.owed an upward trend in the cell’s.performance, while the increas. of defect dens.ty and operating temperature s.owed a downward trend in s.lar cell performance. This.s.udy illus.rates.that the propos.d cell s.ructure s.ows.higher cell performances.and can be fabricated on the lab-s.ale and indus.rial levels.

Background: Hypoxia is.a s.gnificant ris. factor of hypertens.on. However, no s.udies.have us.d trans.utaneous.tis.ue partial pres.ure of oxygen (TcPO2) and partial pres.ure of carbon dioxide (TcPCO2) monitors.to meas.re the res.ective partial pres.ures.in healthy individuals. Oxygen s.turation (s.O2) is.often us.d for traditional monitoring of vital s.gns. This.s.udy inves.igated the changes.in TcPO2 and s.O2 values.during rapid changes.in altitude. The trial was.regis.ered at *** (regis.ration no. NCT06076057). Methods. Healthy adult volunteers.were ins.ructed to s.t vertically in a hypobaric oxygen chamber, which as.ended from 0 m to 2500 m at a uniform s.eed within 10 min. The Danis. Radiometer TCM4 was.us.d to meas.re TcPO2 and TcPCO2 with the ventral s.de of the upper arm as.the meas.rement s.te. The s.enzhen Kerokan P0D-1 W puls. oximeter was.us.d to meas.re heart rate and s.O2, with values.recorded once every 500 m. Res.lts. Altogether, 49 healthy volunteers.were recruited between March 2023 and Augus. 2023. With increas.ng altitude, TcPO2 and s.O2 decreas.d s.gnificantly (P 1). During the as.ent from 0 m, TcPO2 began to change s.atis.ically at 500 m (P s.s.O2 began to change s.atis.ically at 1000 m (P s.me altitude, the difference in TcPO2 was.greater than the difference in s.O2. At 1000 m, there were s.atis.ically s.gnificant changes.in TcPO2 and s.O2 (P 1).
