Highly conductive charge transport layers impair charge extraction selectivity in thin-film solar cells
Mathias Nyman, Christian Ahläng, Staffan Dahlström +6
Charge selective interlayers are crucial in thin-film photovoltaics, such as organic and Perovskite solar cells. Charge transporting layers (doped and undoped) constitute perhaps t…
Cross-Linking of Doped Organic Semiconductor Interlayers for Organic Solar Cells: Potential and Challenges
Staffan Dahlström, Sebastian Wilken, Yadong Zhang +5
Solution-processable interlayers are an important building block for the commercialization of organic electronic devices such as organic solar cells. Here, the potential of cross-l…
How to Reduce Charge Recombination in Organic Solar Cells: There Are Still Lessons to Learn from P3HT:PCBM
Sebastian Wilken, Dorothea Scheunemann, Staffan Dahlström +3
Suppressing charge recombination is key for organic solar cells to become commercial reality. However, there is still no conclusive picture of how recombination losses are influenc…
Impact of a doping-induced space-charge region on the collection of photo-generated charge carriers in thin-film solar cells based on low-mobility semiconductors
Oskar J. Sandberg, Staffan Dahlström, Mathias Nyman +3
Unintentional doping of the active layer is a source for lowered device performance in organic solar cells. The effect of doping is to induce a space-charge region within the activ…
