Result description
The layout of the demonstrator module was formed by 15 series connected cells with a cell width of 4.5mm. An optimised condition for P1-P2-P3 laser ablations was used to pattern the modules. The results show an active area (47.2 cm2) efficiency of 15% for a module fabricated with planar architecture on a SnO2 electron transporting layer and substrate area of 10×10 cm2. A Maximum Power Point tracking was used to assess the stabilised efficiency of the module which results to be equal to 12% after 180s.
The improvement of photovoltaic (PV) parameters on substrate areas equal to 10×10 cm2 is an important requirement for the further development of perovskite photovoltaic technology and to achieve the final scaling-up needed for commercialisation. The demonstration of mini-modules produced with up-scalable processes and materials are equally important to demonstrate the potential of perovskite photovoltaics technology outside the laboratory and beyond the realm of academic research. This result is therefore not only targeting PV researchers.
Summary:
- 10×10 cm2 perovskite single-junction module with an initial active area efficiency of 14% and 12% steady-state efficiency
- Demonstrated scalability of single-junction perovskite-based solar cell, using industrially compatible processes
- Full laser patterning allowing for minimal dead areas
- Both NIP and PIN single-junction perovskite modules with steady state efficiency above 12% relying on industrial deposition processes
