| Design of Experiments and Machine Learning-Assisted Organic Solar Cell Efficiency OptimizationOrganic solar cells (OSCs) represent a cost-effective way to transform solar energy into electricity due to their potential for low-cost and high-throughput roll-to-roll production.[1] Improving OSC efficiency and stability are two of the most important tasks on the way toward commercialization. While much effort has been focused on developing new materials, there is enormous room with respect to optimization of the processing of OSCs to achieve optimal performance of a particular photoactive material. Morphology of the bulk heterojunction, the most important layer within an OSC, results from nanoscale phase segregation that depends extensively upon processing. However, the optimization process for an OSC is tedious, time-consuming and expensive involving many parameters. Conventional optimization uses unimodal approach where one parameter is optimized while all others are kept constant. This can take months or years. Moreover, there is an associated risk of missing the optimal results because all experimental combinations for all parameters cannot be performed. Herein, we report an approach that uses Design of Experiments (DOE) along with machine learning statistical data analysis to effectively and efficiently optimize solar cell efficiency. Machine learning algorithms are trained to find patterns in datasets which could greatly assist data analysis and parameter importance evaluation, hence predict the results for future experiments.[2] DOE methods allow experimentalists to explore a larger parameter space with fewer experimental trials while obtaining valid and objective conclusions. We show that, using the principles of DOE to plan experiments combined with using machine learning assist in the prediction of optimized solar cells. Specific examples of concrete improvement of the power conversion efficiency of OSCs will be described.

| Machine-Learning and Design of Experiments-based Optimization of Organic Solar CellsOver the coming decades, global population and energy consumption are projected to increase dramatically, with the latter doubling by 2050 as per the most conservative estimates. Much of this demand is likely to be met with increased use of fossil fuels. The burning of fossil fuels is a major contributor to the ever-increasing CO 2 concentration in the atmosphere, a major driver of climate change. In order for countries and companies to meet their climate targets, they must undergo a transition to low or CO 2 -free energy sources (wind, solar, hydroelectric, for example). Solar power, typically harvested using photovoltaic and solar thermal devices, is considered one of the most promising renewable energy technologies due to the sheer quantity of solar irradiation impinging upon terrestrial earth. Organic photovoltaics (OPVs) are a subset of PV technology that are thin, lightweight, printable using roll-to-roll and spray coating technologies, flexible, and can be made semi-transparent. These features enable this class of photovoltaics to be considered in markets and locales otherwise inaccessible to traditional silicon devices, which are heavy and cumbersome. Organic photovoltaics comprise many layers that need to be manufactured with great care in order to yield devices capable of producing substantial power, in a reproducible fashion. The central layer in this stack is the critical light absorbing layer that consists of two or three, and occasionally more, different organic molecules. | Publication | 2020-08-31 | Aaron Kirkey |

| Mechanochemical Synthesis of Methylammonium Lead Mixed\textendash Halide Perovskites: Unraveling the Solid-Solution Behavior Using Solid-State NMRMixed-halide lead perovskite (MHP) materials are rapidly advancing as next-generation high-efficiency perovskite solar cells due to enhanced stability and bandgap tunability. In this work, we demonstrate the ability to readily and stoichiometrically tune the halide composition in methylammonium-based MHPs using a mechanochemical synthesis approach. Using this solvent-free protocol we are able to prepare domain-free MHP solid solutions with randomly distributed halide ions about the Pb center. Up to seven distinct [PbClxBr6–x]4– environments are identified, based on the 207Pb NMR chemical shifts, which are also sensitive to the changes in the unit cell dimensions resulting from the substitution of Br by Cl, obeying Vegard’s law. We demonstrate a straightforward and rapid synthetic approach to forming highly tunable stoichiometric MHP solid solutions while avoiding the traditional solution synthesis method by redirecting the thermodynamically driven compositions. Moreover, we illustrate the importance of complementary characterization methods, obtaining atomic-scale structural information from multinuclear, multifield, and multidimensional solid-state magnetic resonance spectroscopy, as well as from quantum chemical calculations and long-range structural details using powder X-ray diffraction. The solvent-free mechanochemical synthesis approach is also compared to traditional solvent synthesis, revealing identical solid-solution behavior; however, the mechanochemical approach offers superior control over the stoichiometry of the final mixed-halide composition, which is essential for device engineering.

| Plexcitonics – Fundamental principles and optoelectronic applicationsThe nanoscale confinement and coupling of electromagnetic radiation into plexcitonic modes has drawn immense interest because of the innovative possibilities for their application in light harvesting and light emitting devices (LEDs). Plexcitons arise from the coupling between two types of quasiparticles, plasmons and excitons, and can be distinguished by the strength of the coupling into strong and weak coupling regimes. Plexcitons have been used to modulate the rate of Förster-type resonance energy transfer in quantum dot assemblies and enhance the spontaneous emission rate in quantum dot LEDs. The clearest examples of a plexcitonic enhancement of photocatalytic reaction rates have been evidenced in hybrid systems wherein the strongly bound exciton found in 2D sheet-like semiconductors is coupled to the surface plasmon resonance of close-lying noble metal nanoparticles. Plexcitonic photocatalysts and solar cells aim to increase the lifetime of hot carriers and thereby enhance the quantum yields for energy harvesting. Since plexcitonics requires the placement of plasmonic and excitonic components in close proximity with one another to facilitate their coupling, it provides a rich arena for chemists and materials scientists to form deterministic and non-deterministic arrays and heterojunctions involving noble metal thin films and nanostructures, quantum dots and dye molecules. This review summarizes the dynamics of plexcitons in the various composite systems and provides an overview of the latest theoretical and experimental developments in the field of plexcitonics. | Publication | 2019-01-02 | Ajay Manuel, Aaron Kirkey, Najia Mahdi, Karthik Shankar |

| Unusual Surface Ligand Doping-Induced p-Type Quantum Dot Solids and Their Application in Solar CellsDoping quantum dots (QDs) is a problem that has been haunting researchers in the QD research community for years, even though doping techniques have been utilized for decades in conventional semiconductors. For the “self-purification” in colloidal QDs, engineering the surface ligands has emerged as an effective way to alter free carrier concentrations and doping types in colloidal QD solids. Halide-atomic ligands are the most popular ligands in producing PbS QD solids since they provide minimal dot-to-dot distance while maintain low in-gap trap states. However, previously reported halide surface treatment could only produce n-type QD solids. Here, we report the fabrication of p-type PbS QD solids using proton-assisted surface ligand exchange. We unveiled the origin of p-type doing in PbS QD solids, and it came from an unusual surface ligand; the HOH+ group formed using NH4X (X = Cl, Br, I) in methanol. We further fabricated QD solar cells using PbS–NH4Cl, a p-type QD solid predicted and proved by our theory and experiments. The champion device shows a high power conversion efficiency of 7.49%. | Publication | 2020-11-01 | Lingju Meng, Qiwei Xu, Ujwal Thakur, Lu Gong, Hongbo Zeng, Karthik Shankar, Xihua Wang |
