Abstract

A modified chemical surface deposition (mCSD) method was introduced to confirm the advantages of buffer layers deposited heterogeneously using a solution process mechanism. In chemical bath deposition (CBD), an absorber is immersed in a mixed aqueous solution containing all cation and anion precursors; in chemical surface deposition (CSD), only the absorber surface participates in the reaction using mixed precursor solutions; and in mCSD, each cation and anion precursor reacts separately on the absorber surface, resulting in a heterogeneous reaction. Optimum conditions to form a buffer layer via a heterogeneous reaction in the mCSD process are determined by changing the deposition order of the precursor solution and solution combination. The CdS or Zn(S,O,OH) buffer layers formed under optimal mCSD conditions indicated higher photovoltaic performance in solar cells compared to that of the conventional CdS buffer layer formed by the CBD method. Temperature-dependent photovoltaic characteristics, capacitance–voltage measurements, and drive-level capacitance profiling were performed to investigate carrier transport behaviors, confirming that the solar cell with mCSD-CdS had less interface recombination. Further, the admittance spectroscopy for defect analysis indicated that a solar cell with the mCSD-processed buffer layer did not form deep defects compared to that with the CBD-processed buffer layer.

有意诱导非均相反应形成缓冲层对CIGS太阳能电池的影响
介绍了一种改进的化学表面沉积(mCSD)方法,以证实采用溶液过程机理沉积非均质缓冲层的优越性。在化学浴沉积(CBD)中,吸收剂浸泡在含有所有阳离子和阴离子前体的混合水溶液中;在化学表面沉积(CSD)中,使用混合前驱体溶液,只有吸收剂表面参与反应;在mCSD中,每个阳离子和阴离子前体分别在吸收剂表面发生反应,产生非均相反应。通过改变前驱体溶液和溶液组合的沉积顺序,确定了在mCSD过程中通过非均相反应形成缓冲层的最佳条件。在最佳mCSD条件下形成的CdS或Zn(S,O,OH)缓冲层与CBD方法形成的传统CdS缓冲层相比,在太阳能电池中具有更高的光伏性能。通过温度相关的光伏特性、电容电压测量和驱动级电容分析来研究载流子输运行为,证实了mcsd - cd太阳能电池具有较少的界面重组。此外,用于缺陷分析的导纳光谱表明,与cbd处理的缓冲层相比,mcsd处理的太阳能电池没有形成深度缺陷。

期刊介绍: Solar RRL, formerly known as Rapid Research Letters, has evolved to embrace a broader and more encompassing format. We publish Research Articles and Reviews covering all facets of solar energy conversion. This includes, but is not limited to, photovoltaics and solar cells (both established and emerging systems), as well as the development, characterization, and optimization of materials and devices. Additionally, we cover topics such as photovoltaic modules and systems, their installation and deployment, photocatalysis, solar fuels, photothermal and photoelectrochemical solar energy conversion, energy distribution, grid issues, and other relevant aspects. Join us in exploring the latest advancements in solar energy conversion research.
