Abstract

In this paper, a polycrystalline cadmium telluride/silicon ( CdTe / Si ) solar cell based on SiO 2 / TiO 2 distributed Bragg reﬂector (DBR) is proposed and investigated using calibrated simulations with experimental data of previous fabrication device. At ﬁrst, by inserting the SiO 2 / TiO 2 DBR, the conversion eﬃciency is increased by about 25 % compared with the conventional CdTe / Si solar cell with similar dimen-sions. In addition, the carrier lifetime of absorber layer can provide an improved conversion eﬃciency of 15% compared with the CdTe / Si conventional solar cell. The obtained open circuit voltage, short circuit current density, ﬁll factor and con-versioneﬃciencyofproposedsolarcellstructurewereabout 1 . 2 V, 39 . 5 mA / cm 2 , 0 . 95 and 28 . 5% under global AM 1 . 5 conditions, respectively. The results strongly con-ﬁrm that the polycrystalline CdTe / Si solar cell based on SiO 2 / TiO 2 DBR seems to be the most optimal choice for converting the solar energy in high eﬃciency photovoltaics systems. conﬁrman que la celda solar policristalina CdTe / Si basada en SiO 2 / TiO 2 DBR es una opción más óptima para convertir la energía solar en sistemas fotovoltaicos de alta eﬁciencia.

利用SiO2/TiO2分布式Bragg反射器设计CdTe/Si串联太阳能电池

本文提出了一种基于二氧化硅/二氧化钛分布式布拉格反射器(DBR)的多晶碲化镉/硅(CdTe / Si)太阳能电池，并利用前人制备装置的实验数据进行了标定模拟研究。首先，通过插入sio2 / tio2 DBR，与同等尺寸的传统CdTe / Si太阳能电池相比，转换效率提高了约25%。此外，吸收层的载流子寿命可以提供比CdTe / Si传统太阳能电池提高15%的转换效率。所得的开路电压、短路电流密度、填充系数和转换效率均约为1。2:39。5毫安/厘米2,095和28。全球AM 1下5%。5个条件。结果有力地证实了基于sio2 / tio2 DBR的多晶CdTe / Si太阳能电池似乎是高效光伏系统中太阳能转换的最佳选择。确认的que la celda solar politicstalina CdTe / Si basada en sio2 / tio2 DBR是una opción más óptima para转换器la energía太阳能系统的fotovoltaicos de alta效率。(DBR)。
