Abstract

Silicon nanoparticles (SiNPs) were synthetized and employed in self-embedded films as luminophore to fabricate transparent luminescent solar concentrators (SiNPLSCs). The nanoparticles were obtained from the reduction of (3-aminopropyl) triethoxysilane (APTES) by sodium ascorbate. Besides the reduction of APTES into SiNPs, a silicate matrix host is obtained and further employed as the nanoparticles support for the photoluminescent film. The SiNPs exhibit absorption below 450 nm extending to the ultraviolet region; while emitting in broad bands from 400 to 650 nm, whose maximum depends on the excitation wavelength. The as-synthesized solution containing both the SiNPs and the matrix host was deployed directly on glass substrates to create the SiNPLSCs. The devices present high transparencies with transmittances above 85% over the visible region, producing average visible transmission (AVT) values of 88.78% and great color rendering index (CRI) of 98.26. The photoluminescent properties of the SiNPLSCs were measured at the edges of the devices under different excitation wavelengths and solar simulated light. The LSCs were physically attached to commercial silicon solar cells (PV) to study the photovoltaic performance of the LSC-PV systems. According to I-V measurements under solar simulated light, the SiNPLSC-PV system showed power conversion efficiency of 0.97% and optical efficiency of 1.04%. These results are significant since the device presents high transparency with a feasible and attractive fabrication method, properties that are desired for their incorporation as building integrated photovoltaics and photovoltaic windows.

用于透明发光太阳能聚光器的自嵌入硅纳米颗粒薄膜

合成了硅纳米粒子（SiNPs），并将其作为发光团应用于自嵌入薄膜中制备透明发光太阳能聚光器（SiNPLSCs）。纳米粒子是由抗坏血酸钠还原（3-氨基丙基）三乙氧基硅烷（APTES）得到的。除了将APTES还原为SiNPs外，还获得了硅酸盐基质载体，并进一步用作光致发光膜的纳米颗粒载体。SiNPs表现出450 nm以下的吸收，延伸到紫外区；在400 ~ 650 nm的宽波段发射，其最大值取决于激发波长。将含有SiNPs和基质主体的合成溶液直接部署在玻璃基板上以创建SiNPLSCs。该器件具有较高的透明度，在可见光区域的透过率在85%以上，平均可见光透过率（AVT）为88.78%，显色指数（CRI）为98.26。在不同的激发波长和太阳模拟光下，在器件边缘测量了SiNPLSCs的光致发光特性。将LSCs物理附着在商用硅太阳能电池（PV）上，研究LSCs -PV系统的光伏性能。根据太阳模拟光下的I-V测量，SiNPLSC-PV系统的功率转换效率为0.97%，光效率为1.04%。这些结果是重要的，因为该器件具有高透明度，具有可行且有吸引力的制造方法，这些特性是建筑集成光伏和光伏窗户所需要的。

期刊介绍： The journal Silicon is intended to serve all those involved in studying the role of silicon as an enabling element in materials science. There are no restrictions on disciplinary boundaries provided the focus is on silicon-based materials or adds significantly to the understanding of such materials. Accordingly, such contributions are welcome in the areas of inorganic and organic chemistry, physics, biology, engineering, nanoscience, environmental science, electronics and optoelectronics, and modeling and theory. Relevant silicon-based materials include, but are not limited to, semiconductors, polymers, composites, ceramics, glasses, coatings, resins, composites, small molecules, and thin films.
