In this study, the hybrid solar cells (HSCs) were fabricated with high-purity nano Si from nano SiO precursor extracted from natural minerals, that is, quartz sand. The prepared nano Si was used as an electron transport material to prepare an active layer material mixture with poly(3-hexylthiophene) (P3HT) by mixing it in two composition ratios, namely 1 : 1 and 1 : 0.8. The blended active layer solutions (ALSs) were prepared by using solvents such as 1,2-dichlorobenzene (DCB), chlorobenzene (CB), and chloroform (CF). The HSCs were fabricated using six blended ALSs, namely ALS1, ALS2, ALS3, ALS4, ALS5, and ALS6. The current density-voltage characteristics of the fabricated HSCs were studied using a simulated AM 1.5G illumination having light density power of 100 mW cm. The characterization properties such as short circuit current density ( ) and power conversion efficiency (PCE) were studied and compared with those of all six HSCs fabricated with six blended ALSs. At the outset, the P3HT : nano-Si (1 : 0.8) blended ALS in CB solvent shows 2.37% PCE, and 46% of external quantum efficiency (EQE) absorption which is higher than the other fabricated solar cells. This study discusses the possibilities of preparation of nano Si from natural mineral sand, as an effective electron transport material to fabricate HSCs with enhanced PCE.
在本研究中，混合太阳能电池（HSCs）是用从天然矿物（即石英砂）中提取的纳米SiO前驱体制备的高纯度纳米Si制造的。制备的纳米Si用作电子传输材料，通过以两种组成比（即1∶1和1∶0.8）将其与聚（3-己基噻吩）（P3HT）混合来制备活性层材料混合物。使用诸如1,2-二氯苯（DCB）、氯苯（CB）和氯仿（CF）等溶剂制备混合活性层溶液（ALSs）。使用六种混合ALS（即ALS1、ALS2、ALS3、ALS4、ALS5和ALS6）制造HSCs。使用具有100 mW cm光密度功率的模拟AM 1.5G光照研究制造的HSCs的电流密度-电压特性。研究了诸如短路电流密度（ ）和功率转换效率（PCE）等表征特性，并与用六种混合ALS制造的所有六种HSCs的表征特性进行了比较。一开始，CB溶剂中的P3HT∶纳米Si（1∶0.8）混合ALS显示出2.37%的PCE和46%的外量子效率（EQE）吸收，高于其他制造的太阳能电池。本研究讨论了从天然矿物砂制备纳米Si作为有效电子传输材料以制造具有增强PCE的HSCs的可能性。
