Interdot Lead Halide Excess Management in PbS Quantum Dot Solar Cells
Miguel Albaladejo-Siguan, David Becker-Koch, Elizabeth C. Baird +7
Light-harvesting devices made from PbS quantum dot (QD) absorbers are one of the many promising technologies of third-generation photovoltaics. Their simple, solution-based fabrica…
Influence of chemical interactions on the electronic properties of BiOI/organic semiconductor heterojunctions for application in solution-processed electronics
Vaidehi Lapalikar, Preetam Dacha, Mike Hambsch +4
Bismuth oxide iodide (BiOI) has been viewed as a suitable environmentally-friendly alternative to lead-halide perovskites for low-cost (opto-)electronic applications such as photod…
Towards low-temperature processing of efficient -CsPbI perovskite solar cells
Zongbao Zhang, Ran Ji, Yvonne J. Hofstetter +5
Inorganic cesium lead iodide (CsPbI) perovskite solar cells (PSCs) have attracted enormous attention due to their excellent thermal stability and optical bandgap (~1.73 eV), we…
Remarkable performance recovery in highly defective perovskite solar cells by photo-oxidation
Katelyn P. Goetz, Fabian T. F. Thome, Qingzhi An +8
Exposure to environmental factors is generally expected to cause degradation in perovskite films and solar cells. Herein, we show that films with certain defect profiles can displa…
Bis(stearoyl) Sulfide: A Stable, Odor-free Sulfur Precursor for High-Efficiency Metal Sulfide Quantum Dot Photovoltaics
Miguel Albaladejo-Siguan, Anatol Prudnikau, Alina Senina +6
The synthesis of metal sulfide nanocrystals is a crucial step in the fabrication of quantum dot (QD) photovoltaics. Control over the quantum dot size during synthesis allows for pr…
Perovskite Phase Heterojunction Solar Cells
Ran Ji, Zongbao Zhang, Yvonne J. Hofstetter +4
Modern photovoltaic devices are often based on a heterojunction structure where two components with different optoelectronic properties are interfaced. The properties of each side…
Intermolecular charge transfer enhances the performance of molecular rectifiers
Ryan P. Sullivan, John T. Morningstar, Eduardo Castellanos +5
Molecular-scale diodes made from self-assembled monolayers (SAMs) could complement silicon-based technologies with smaller, cheaper, and more versatile devices. However, advancemen…
Traps and transport resistance: the next frontier for stable state-of-the-art non-fullerene acceptor solar cells
Christopher Wöpke, Clemens Göhler, Maria Saladina +17
Stability is one of the most important challenges facing organic solar cells (OSC) on their path to commercialization. In the high-performance material system PM6:Y6 studied here,…
A General Approach to High Efficiency Perovskite Solar Cells by Any Antisolvent
Alexander D. Taylor, Qing Sun, Katelyn P. Goetz +6
Deposition of perovskite thin films by antisolvent engineering is one of the most common methods employed in perovskite photovoltaics research. Herein, we report on a general metho…
Energy Level Alignment in Ternary Organic Solar Cells
