Upscaling of Perovskite Photovoltaics

Thermally controlled growth of photoactive FAPbI3 films for highly stable perovskite solar cells

“…1–3 The recent advance in the stability of the manufactured devices, as a bottleneck of this PV technology, shows a promising way to implement future upscaling. 4–7 However, processing methods, compositional engineering, and other approaches need further development to compete with the most stable PV devices such as silicon solar cells. 8,9 In this effort, the black phase of the FAPbI 3 chemical composition has emerged as one of the most promising within the perovskite halide families to boost the PCE and the final stability of the device under operation.…”

Scalable Passivation Strategies to Improve Efficiency of Slot Die-Coated Perovskite Solar Cells

“…When comparing devices of comparable cell area that were fabricated by lab scale spin coating and scalable printing, a gap in PCE is often observed. − When transitioning to scalable deposition techniques, the kinetics of the nucleation and crystallization processes in the perovskite films can be different than in the rapid spinning process. This difference can result in varying concentrations of defects such as pinholes, cracks, increased surface roughness, less uniform composition distributions, high defect densities, and so on. , It is also important to note that different cell architectures, electrode designs, transparent conductive oxide (TCO) properties, and cell areas can result in different parasitic series resistances that can lead to significant PCE losses for larger dimensioned cells.…”
