Abstract

Ag₂BeSnTe₄ kesterite, an inorganic absorber material, holds significant promise for perovskite solar cells. Traditional approaches utilize intrinsic or mono-doped absorbers, limiting charge transport. This study innovates by introducing a multi-doped architecture, combining Cs₂AgBiBr₆ with n-doped Ag₂BeSnTe₄. Furthermore, we investigate the impact of varying ZnX conductive layers (X = O, S, Se, and Te) on the photovoltaic performance of this novel device structure. This study employs the SCAPS-1D framework to analyze and compare the performance of two tandem solar cells, both comprising (ITO/ZnTe/Cs₂AgBiBr₆/Mo/Au) top and bottom cells. The results demonstrate a significant enhancement in power conversion efficiency from 11.59 % in the homo-junction (top cell) to 29.70 % in the tandem configuration. This improvement is accompanied by a notable increase in fill factor (71.58 %–83.42 %) and open-circuit voltage (0.289 V–1.227 V). These findings underscore the substantial benefits of multi-doping of the absorber and the conductive layer in achieving significantly higher efficiency in tandem solar cell architectures.

新型单片2端kesterite Cs2AgBiBr6/Ag2BeSnTe4串联太阳能电池效率29%

Ag2BeSnTe4 kesterite是一种无机吸收材料，在钙钛矿太阳能电池中具有重要的应用前景。传统的方法利用本征吸收剂或单掺杂吸收剂，限制电荷输运。该研究的创新之处是引入了一种多掺杂结构，将Cs2AgBiBr6与n掺杂Ag2BeSnTe4结合在一起。此外，我们研究了不同的ZnX导电层（X = O， S， Se和Te）对这种新型器件结构的光伏性能的影响。本研究采用SCAPS-1D框架分析和比较了两种串联太阳能电池的性能，这两种电池都由（ITO/ZnTe/Cs2AgBiBr6/Mo/Au）顶部和底部电池组成。结果表明，功率转换效率显著提高，从同质结（顶部电池）的11.59%提高到串联结构的29.70%。这一改进伴随着填充系数（71.58% - 83.42%）和开路电压（0.289 V - 1.227 V）的显著增加。这些发现强调了吸收层和导电层的多掺杂在串联太阳能电池结构中实现显着提高效率的实质性好处。

期刊介绍： The Journal of Physics and Chemistry of Solids is a well-established international medium for publication of archival research in condensed matter and materials sciences. Areas of interest broadly include experimental and theoretical research on electronic, magnetic, spectroscopic and structural properties as well as the statistical mechanics and thermodynamics of materials. The focus is on gaining physical and chemical insight into the properties and potential applications of condensed matter systems. Within the broad scope of the journal, beyond regular contributions, the editors have identified submissions in the following areas of physics and chemistry of solids to be of special current interest to the journal: Low-dimensional systems Exotic states of quantum electron matter including topological phases Energy conversion and storage Interfaces, nanoparticles and catalysts.
