光捕获方案的最新进展为增强太阳能的吸收开辟了新的途径，该途径接近并克服了基于各向同性朗伯散射体的Yablonovitch 4n2极限。实现宽角散射的同时保持强散射强度是实现具有接近吸收上限的巨大潜力的类朗伯散射体的关键。然而，目前很少有光捕获策略可以在实验上扩展吸收体中的散射角域，同时保持高散射强度。本文从理论和实验两方面研究了多尺寸透明导电氧化物（TCO）薄膜的制备方法，该薄膜由磁控溅射和化学刻蚀的微米级掺铝氧化锌（ZnO：Al）和金属有机化学气相沉积（MOCVD）沉积的纳米级掺硼氧化锌（ZnO：B）金字塔组成。结果表明，该研究中的多尺寸TCO可以有效地提高可见光谱范围内的总透射率，增强散射强度，成功地将散射角域扩展到90°，并提高太阳能电池的短路电流密度和功率输出。这些因素的组合赋予TCO实现朗伯类散射体的显着潜力。因此，多尺寸架构可能会激发新的想法，以实现更创新的陷光架构。
Recent advances in light trapping schemes open up new gateways for enhancing the absorption of solar energy that approaches and overcomes the Yablonovitch 4n2limit based on isotropic Lambertian scatterers. Achieving wide-angular scattering while maintaining a strong scattering intensity is the key to realize a Lambertian-like scatterer that may have a great potential to approach the absorption upper limit. However, few current light trapping strategies can experimentally extend the scattering angular domains in absorbers while maintaining a high scattering intensity. In this paper, we theoretically and experimentally investigate multi-sized transparent conducting oxide (TCO) films, which are comprised of micro-sized, magnetron-sputtered and chemically etched aluminum-doped zinc oxide (ZnO:Al), coated with metal organic chemical vapor deposition (MOCVD) deposited nano-sized, boron-doped zinc oxide (ZnO:B) pyramids. We demonstrate that the multi-sized TCOs in this study can efficiently increase the total transmittance in the visible spectral range, enhance the scattering intensity, successfully extend the scattering angular domains to 90°, and improve the short-circuit current density and power output of solar cells. The combination of these factors endows the TCOs with the significant potential for realizing a Lambertian-like scatterer. Accordingly, the multi-sized architecture may inspire fresh ideas for realizing more innovative light-trapping architectures.
