Molybdenum disulfide (MoS2)/cadmium sulfide (CdS) heterojunction solar cells were successfully synthesized via chemical bath deposition (CBD) and chemical vapor deposition (CVD). The as-grown CdS film on a fluorine tin oxide (FTO) substrate deposited by CBD is continuous and compact. The MoS2 film deposited by CVD is homogeneous and continuous, with a uniform color and a thickness of approximately 10 nm. The optical absorption range of the MoS2/CdS heterojunction covers the visible and near-infrared spectral regions of 350 to 800 nm, which is beneficial for the improvement of solar cell efficiency. Moreover, the MoS2/CdS solar cell exhibits good current-voltage (I-V) characteristics and pronounced photovoltaic behavior, with an open-circuit voltage of 0.66 V and a short-circuit current density of 0.227 × 10(-6) A/cm(2), comparable to the results obtained from other MoS2-based solar cells. This research is critical to investigate more efficient and stable solar cells based on graphene-like materials in the future.
二硫化钼 (MoS2)/硫化镉 (CdS) 异质结太阳能电池通过化学浴沉积 (CBD) 和化学气相沉积 (CVD) 成功合成。通过 CBD 在氟掺杂氧化锡 (FTO) 基底上生长的 CdS 薄膜连续且致密。通过 CVD 沉积的 MoS2 薄膜均匀且连续，颜色均匀，厚度约为 10nm。MoS2/CdS 异质结的光吸收范围涵盖了 350 至 800nm 的可见光和近红外光谱区域，有利于提高太阳能电池的效率。此外，MoS2/CdS 太阳能电池表现出良好的电流-电压 (I-V) 特性和明显的光伏行为，开路电压为 0.66V，短路电流密度为 0.227×10(-6)A/cm(2)，与其他基于 MoS2 的太阳能电池的结果相当。这项研究对于未来研究基于类石墨烯材料的更高效、更稳定的太阳能电池具有重要意义。
