n.merical An.lysis on.the Effect of n.Si on.Cu(In. Ga)Se₂ Based Thin.Films for High-Perfor.ance Solar Cells by 1D-SCAPS

引用

Open.Journ.l of Applied Scien.es 2024年第5期14卷 1315-1329页

作者： rasika n. Mohottige Micheal Farn.ale Gary S. Coombs Shahn.za Saburhhojayeva Departmen. of n.tural Scien.es Waldorf University Forest City IA USA

We report the perfor.ances 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.and win.ow layers, respectively. The optimum CIGS ban.gap was determin.d first an. used to simulate an. an.lyze the cell perfor.ance 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 perfor.ance 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 perfor.ance, while the in.rease of defect den.ity an. operatin. temperature showed a down.ard tren. in.solar cell perfor.ance. This study illustrates that the proposed cell structure shows higher cell perfor.ances an. can.be fabricated on.the lab-scale an. in.ustrial levels.

An.malous ion.heat tran.port is an.lyzed in.the T-10 tokamak plasma heated with electron.cyclotron.reson.n.e heatin.(ECrH) in.secon.-harmon.c extra-ordin.ry mode. Predictive modelin. with empirical scalin. for Ohmical heat con.uctivity shows that in.ECrH plasmas the calculated ion.temperature could be overestimated, so an.in.rease of an.malous ion.heat tran.port is required. To study this effect two scan. are presen.ed: over the EC reson.n.e position.an. over the ECrH power. The EC reson.n.e position.varies from the high-field side to the low-field side by variation.of the toroidal magn.tic field. The scan.over the heatin. power is presen.ed with on.axis an. mixed ECrH regimes. Discharges with high an.malous ion.heat tran.port are obtain.d in.all con.idered regimes. In.these discharges the power balan.e ion.heat con.uctivity exceeds the n.oclassical level by up to 10 times. The high ion.heat tran.port regimes are distin.uished by three parameters: the ratio Te/Ti, the n.rmalized electron.den.ity gradien. r/■, an. the ion.ion.collision.lity νii~*. The combin.tion.of high Te/Ti, high νii~*, an. r/■=6-10 results in.values of n.rmalized an.malous ion.heat fluxes up to 10 times higher than.in.the low tran.port scen.rio.
