The increasing demand for solar energy has led researchers worldwide to develop new photovoltaic technologies. Among these, perovskite materials are one of the most promising candidates, with a performance evolution unparalleled in the photovoltaic field. However, this thin-film technology is not yet available at a commercial level, mainly due to upscaling issues. This work studied the best design options for upscaling single cells into modules by minimizing electrical losses in the device substrates. The software LAOSS was used to test and optimize different substrate sizes and designs and to predict several performance outcomes from experimentally fabricated single cells. The results showed that it is possible to retain most of the energy production when upscaling from a single cell to a module if the appropriate design for an efficient monolithic device is used. The width of the interconnection zone also plays an important role in device performance and must be carefully optimized during module design. It then demonstrates the importance of having precise laser tools, which are essential for narrow and smooth scribes, and how useful simulation software can be, which, combined with experimental developments, will facilitate efficient module fabrication, aiming to establish it as a feasible and marketable resource.
对太阳能日益增长的需求促使全球研究人员开发新的光伏技术。其中，钙钛矿材料是最有前景的候选材料之一，其性能发展在光伏领域无与伦比。然而，这种薄膜技术尚未达到商业应用水平，主要是由于放大问题。这项工作研究了通过最小化器件基板中的电损耗将单电池放大为模块的最佳设计方案。使用软件LAOSS来测试和优化不同的基板尺寸和设计，并从实验制造的单电池预测几种性能结果。结果表明，如果使用高效单片器件的适当设计，从单电池放大到模块时可以保留大部分能量产生。互连区的宽度在器件性能中也起着重要作用，在模块设计过程中必须仔细优化。然后展示了拥有精确激光工具的重要性，这对于窄而平滑的划线至关重要，以及模拟软件的实用性，模拟软件与实验开发相结合，将有助于高效的模块制造，旨在将其确立为一种可行且可销售的资源。
