Title: | Organic indoor PV: vanishing surface recombination allows for robust device architecture | Authors: | JIANG, Xueshi SIEGMUND, Bernhard VANDEWAL, Koen |
Issue Date: | 2024 | Publisher: | ROYAL SOC CHEMISTRY | Source: | Materials Horizons, | Status: | Early view | Abstract: | As a promising candidate to drive low-power, off-grid applications, organic indoor photovoltaics are beginning to attract research and commercial attention. In organic photovoltaic devices, charge transport layers are often used to promote the extraction of majority carriers, while blocking minority carriers. They can however be a source of device degradation and introduce additional complexity to the fabrication of the device stack. Here, a simplified, yet performant indoor OPV architecture is demonstrated with extended absorber thickness and without electron transport layer (ETL). We show that the diminished impact of the ETL on indoor OPV results from a drastically reduced surface recombination in thick absorber devices. However, the ETL remains important under strong, outdoor illumination, since in that case the reduced surface recombination is overwhelmed by bulk recombination. The proposed simplified device architecture with thick absorber (>500 nm) has great potential in large-scale production of indoor OPV. | Notes: | Jiang, XS; Siegmund, B; Vandewal, K (corresponding author), Hasselt Univ, Inst Mat Res Imo Imomec, Martelarenlaan 42, B-3500 Hasselt, Belgium.; Jiang, XS; Siegmund, B; Vandewal, K (corresponding author), Imec, Imo Imomec, Wetenschapspk 1, B-3590 Diepenbeek, Belgium.; Jiang, XS; Siegmund, B; Vandewal, K (corresponding author), EnergyVille, Imo Imomec, Thor Pk 8320, B-3600 Genk, Belgium. xueshi.jiang@uhasselt.be; bernhard.siegmund@uhasselt.be; koen.vandewal@uhasselt.be |
