The rapid pace of urban.developmen. has resulted in.the widespread presen.e of con.truction.equipmen. an.in.reasin.ly complex con.ition. in.tran.mission.corridors. These con.ition. pose a serious threat to the safeoperation.of the power *** vision.techn.logy, particularly object recogn.tion.techn.logy, has been.idelyemployed to iden.ify foreign.objects in.tran.mission.lin. images. Despite its wide application. the techn.que faceslimitation. due to the complex en.iron.en.al backgroun. an. other auxiliary factors. To address these challen.es,this study in.roduces an.improved YOLOv8n. The tradition.l stepwise con.olution.an. poolin. layers are replacedwith a spatial-depth con.olution.(SPD-Con.) module, aimin. to improve the algorithm’s efficacy in.recogn.zin.low-resolution.an. small-size objects. The algorithm’s feature extraction.n.twork is improved by usin. a LargeSelective Kern.l (LSK) atten.ion.mechan.sm, which en.an.es the ability to extract relevan. features. Addition.lly,the SIoU Loss fun.tion.is used in.tead of the Complete In.ersection.over Un.on.(CIoU) Loss to facilitate fastercon.ergen.e of the algorithm. Through experimen.al verification. the improved YOLOv8n.model achieves adetection.accuracy of 88.8% on.the test set. The recogn.tion.accuracy of cran.s is improved by 2.9%, which isa sign.fican. en.an.emen. compared to the un.mproved algorithm. This improvemen. effectively en.an.es theaccuracy of recogn.zin. foreign.objects on.tran.mission.lin.s an. proves the effectiven.ss of the n.w algorithm.

We report the performan.es of a chalcopyrite Cu(In. Ga)Se2 CIGS-based thin.film solar cell with a n.wly employed high con.uctive n.Si layer. The data an.lysis was performed with the help of the 1D-Solar Cell Capacitan.e Simulator (1D-SCAPS) software program. The n.w device structure is based on.the CIGS layer as the absorber layer, n.Si as the high con.uctive layer, i-In.sub>2S3, an. i-Zn. as the buffer an. win.ow layers, respectively. The optimum CIGS ban.gap was determin.d first an. used to simulate an. an.lyze the cell performan.e throughout the experimen.. This an.lysis revealed that the absorber layer’s optimum ban.gap value has to be 1.4 eV to achieve maximum efficien.y of 22.57%. Subsequen.ly, output solar cell parameters were an.lyzed as a fun.tion.of CIGS layer thickn.ss, defect den.ity, an. the operatin. temperature with an.optimized n.Si layer. The n.wly modeled device has a p-CIGS/n.Si/In.sub>2S3/Al-Zn. structure. The main.objective was to improve the overall cell performan.e while optimizin. the thickn.ss of absorber layers, defect den.ity, ban.gap, an. operatin. temperature with the n.wly employed optimized n.Si layer. The in.rease of absorber layer thickn.ss from 0.2 - 2 µm showed an.upward tren. in.the cell’s performan.e, while the in.rease of defect den.ity an. operatin. temperature showed a down.ard tren. in.solar cell performan.e. This study illustrates that the proposed cell structure shows higher cell performan.es an. can.be fabricated on.the lab-scale an. in.ustrial levels.
