Abstract

The study investigated Au-Ag and Au nanoparticles (NPs) synthesized chemically and added to a commercial conductive carbon paint used as electrodes in Bi2S3/PbS thin-film solar cells. I-V measurements were used for device characterization. NPs were found on the carbon paint surface with sizes of 11.1 ± 0.09 nm to 29 ± 7.5 nm. FFT analysis showed a cubic crystal structure for all NPs. Optically, Au-Ag(1) exhibited broad absorption (363–600 nm), Au-Ag(2) peaked at 546 nm, and Au at 521 nm. Devices with NP-modified electrodes with sizes 29 ± 7.5 nm showed enhanced short-circuit current density (JSC), with Au-Ag(2) reaching 7.19 mA/cm2 and a PCE of 0.46 %, compared to the reference JSC of 3.02 mA/cm2 and PCE of 0.11 %. Series resistance dropped from 23 Ω·cm2 to 2 Ω·cm2 (Au-Ag) and 5 Ω·cm2 (Au).
将金、银、金纳米颗粒掺入碳漆中用于薄膜太阳能电池电极的研究
该研究研究了化学合成的Au- ag和Au纳米颗粒(NPs),并将其添加到商用导电碳漆中,用作Bi2S3/PbS薄膜太阳能电池的电极。I-V测量用于器件表征。在碳漆表面发现了粒径为11.1±0.09 nm ~ 29±7.5 nm的纳米粒子。FFT分析显示所有NPs均为立方晶体结构。在光学上,Au- ag(1)表现出宽吸收(363 ~ 600 nm), Au- ag(2)在546 nm处达到峰值,Au在521 nm处达到峰值。采用尺寸为29±7.5 nm的np修饰电极的器件显示出更高的短路电流密度(JSC),其中Au-Ag(2)达到7.19 mA/cm2, PCE为0.46%,而参考电极的JSC为3.02 mA/cm2, PCE为0.11%。串联电阻从23 Ω·cm2下降到2 Ω·cm2 (Au- ag)和5 Ω·cm2 (Au)。
