Issue Date: | 2024 | Publisher: | WILEY-V C H VERLAG GMBH | Source: | Solar RRL, 8 (15) | Abstract: | Upscaling perovskites modules from laboratory to market specifications requires modules to resist heat, humidity, and partial shading. When a device is partially covered or damaged, the unbalanced photocurrent generated can create an irreversible damage. Mitigation via bypass diodes can be expensive. This might not be necessary for perovskite-based modules. After an initial validation of the finite difference model for a simulation-assisted investigation, a module is systematically damaged and characterized to reproduce an unbalanced photocurrent generation. The device shows a breakdown voltage (< 1 V), which is unexpectedly much lower than for a standalone perovskite cell (approximate to 7 V). The effect is reproducible over time, and it demonstrates that in a reverse bias scenario, electricity can tunnel through the monolithic interconnection (P1P2P3) and operate similar to a low-voltage bypass diode. Eventually, the current and voltage distribution via electroluminescence is mapped to validate the 2D simulations and reproduce the device behavior at different loads. | Notes: | Sala, J (corresponding author), Univ Hasselt, Imo Imomec, Martelarenlaan 42, B-3500 Hasselt, Belgium.; Sala, J (corresponding author), Imo Imomec Partner EnergyVille & Solliance, Thor Pk 8320, B-3600 Genk, Belgium.; Sala, J (corresponding author), Imec EnergyVille, Thor Pk 8320, B-3600 Genk, Belgium. jacopo.sala@uhasselt.be |
