The s.udy inves.igates.long-term changes.in annual and s.as.nal rainfall p.tterns.in the Indira s.gar Region of Madhya p.ades., India, from 1901 to 2010. Agriculture s.s.ainability, food s.p.ly, natural res.urce develop.ent, and hydrop.wer s.s.em reliability in the region rely heavily on mons.on rainfall. Monthly rainfall data from three s.ations.(Eas. Nimar, Barwani, and Wes. Nimar) were analyzed. Initially, the p.e-whitening method was.ap.lied to eliminate s.rial correlation effects.from the rainfall data s.ries. s.bs.quently, s.atis.ical trends.in annual and s.as.nal rainfall were as.es.ed us.ng both p.rametric (s.udent-t tes.) and non-p.rametric tes.s.[Mann-Kendall, s.n’s.s.op. es.imator, and Cumulative s.m (CUs.M)]. The magnitude of the rainfall trend was.determined us.ng Theil-s.n’s.s.op. es.imator. s.0}tial analys.s.of the Mann-Kendall tes. on an annual bas.s.revealed a s.atis.ically ins.gnificant decreas.ng trend for Barwani and Eas. Nimar and an increas.ng trend for Wes. Nimar. On a s.as.nal bas.s. the mons.on s.as.n contributes.a s.gnificant p.rcentage (88.33%) to the total annual rainfall. The CUs.M tes. res.lts.indicated a s.ift change detection in annual rainfall data for Barwani in 1997, while s.ifts.were obs.rved in Wes. and Eas. Nimar s.ations.in 1929. Thes. findings.offer valuable ins.ghts.into regional rainfall behavior, aiding in the p.anning and management of water res.urces.and ecological s.s.ems.

We rep.rt the p.rformances.of a chalcop.rite Cu(In, Ga)s.s.b>2 s.b>CIGs.bas.d thin-film s.lar cell with a newly emp.oyed high conductive n-s. layer. The data analys.s.was.p.rformed with the help.of the 1D-s.lar Cell Cap.citance s.mulator (1D-s.Ap.) s.ftware p.ogram. 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.0}ctively. The op.imum CIGs.bandgap.was.determined firs. and us.d to s.mulate and analyze the cell p.rformance throughout the exp.riment. This.analys.s.revealed that the abs.rber layer’s.op.imum bandgap.value has.to be 1.4 eV to achieve maximum efficiency of 22.57%. s.bs.quently, outp.t s.lar cell p.rameters.were analyzed as.a function of CIGs.layer thicknes., defect dens.ty, and the op.rating temp.rature with an op.imized 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 imp.ove the overall cell p.rformance while op.imizing the thicknes. of abs.rber layers. defect dens.ty, bandgap. and op.rating temp.rature with the newly emp.oyed op.imized n-s. layer. The increas. of abs.rber layer thicknes. from 0.2 - 2 µm s.owed an up.ard trend in the cell’s.p.rformance, while the increas. of defect dens.ty and op.rating temp.rature s.owed a downward trend in s.lar cell p.rformance. This.s.udy illus.rates.that the p.op.s.d cell s.ructure s.ows.higher cell p.rformances.and can be fabricated on the lab-s.ale and indus.rial levels.
