已经研究了用于电流增强的技术以实现高效太阳能电池。纳米结构中的局域表面等离子体共振（LSPR）有望成为这一技术领域的潜在解决方案。特别地，使用溅射在太阳能电池的表面上沉积纳米颗粒由于其低成本和相对简单的方法而变得越来越流行。然而，到目前为止，很少考虑产生高效太阳能电池所需的沉积纳米颗粒的尺寸。在这项研究中，Au纳米粒子沉积在太阳能电池的表面上使用磁控溅射系统。纳米图案特征（例如，粒度、表面覆盖率、粒度分布等）与溅射时间的变化相关。然后，测量所有样品的输出特性。采用卤素灯作为性能评价的光源。结果表明，24 nm的纳米颗粒尺寸显示出最佳性能。24-nm纳米颗粒的最大吸收波长（707 nm）接近所用光源的最大强度波长（701 nm）。这表明，在开发纳米颗粒时，沉积的纳米颗粒的最大吸收波长必须与太阳光的最大强度波长相匹配，以实现高效的太阳能电池。
Techniques for electric current enhancement have been studied to achieve highly efficient solar cells. Localized surface plasmon resonance (LSPR) in nanostructures has promise as a potential solution in this field of technology. In particular, the deposition of nanoparticles on the surface of solar cells using sputtering has become increasingly popular due to its low cost and relatively simple methodology. However, there has so far been little consideration of the size of the deposited nanoparticles required to generate high-efficiency solar cells. In this study, Au nanoparticles were deposited on the surface of solar cells using a magnetron sputtering system. Nano-pattern characteristics (eg, particle size, surface coverage fraction, size distribution, etc.) associated with changes in the sputtering time were evaluated. Then, the output characteristics of all the specimens were measured. A halogen lamp was employed as an optical source for the performance evaluation. The results showed that a nanoparticle size of 24 nm showed the best performance. The maximum absorption wavelength (707 nm) of the 24-nm nanoparticle was close to the maximum intensity wavelength of the optical source used (701 nm). This suggests that when developing nanoparticles, the maximum absorption wavelength of the deposited nanoparticle must be matched with the maximum intensity wavelength of sunlight to realize highly efficient solar cells.
