Designing Tomorrow's Materials
How a Research Consortium is Revolutionizing Materials Chemistry
The Invisible Revolution in Materials Science
Imagine being able to predict a material's properties before ever synthesizing it in a lab, or designing next-generation solar cells not through trial and error, but through sophisticated computational models that peer into the very molecular architecture of matter.
This is the revolutionary world of computational materials chemistry, where the boundaries between the digital and physical realms blur, accelerating scientific discovery at an unprecedented pace.
At the heart of this revolution in the United Kingdom was the Materials Chemistry Consortium (MCC), a collaborative network that brought together leading scientists to harness the power of high-performance computing (HEC) for materials innovation3 . The Steering Committee Report from May to December 2013 captures a critical period in this journey, documenting how coordinated research efforts were paving the way for breakthroughs in fields ranging from clean energy to advanced manufacturing.

The Building Blocks of Matter: Key Concepts in Materials Chemistry
Computational Materials Chemistry
Unlike traditional chemistry that works with flasks and beakers in wet labs, computational materials chemistry uses powerful supercomputers to simulate the behavior of atoms and molecules.
During the 2013 reporting period, the MCC supported a diverse portfolio of projects united by this computational approach. The consortium provided researchers with access to high-performance computing resources and specialized expertise through the Computational Science Centre for Research Communities (CoSeC)3 .
The Stereolithography Connection
While the term "SLA" in the consortium's name more likely refers to the steering committee structure, an interesting parallel exists with Stereolithography (SLA) in advanced manufacturing—a technology that shares the computational-driven philosophy of the consortium's work.
This connection highlights a broader trend in materials science: the integration of digital design with physical production1 .
Research Framework
The MCC functioned as a collaborative hub, bringing together researchers from different institutions to tackle complex materials challenges that would be difficult for any single group to address independently.
The consortium's work exemplified the principles of additive manufacturing described in SLA research, which "is essential in Industry 4.0 as it can produce customized products, lower costs for small and medium-sized production runs and has the ability to reuse materials"1 .

Spotlight on Innovation: The Hybrid Perovskite Investigation
The Quest for Better Solar Materials
One of the most promising research directions during this period involved hybrid perovskite materials for photovoltaic applications. These materials had recently emerged as a potential game-changer for solar energy, offering high conversion efficiencies at potentially lower production costs than traditional silicon solar cells.
The specific investigation referenced in the MCC website's banner image was "inspired by Y. Wang et al, Nat. Photon., 16, 235 (2022)"3 —indicating that work begun during the consortium's activities contributed to long-term research eventually published nearly a decade later.
Perovskite solar cells represent a promising alternative to traditional silicon photovoltaics.
Methodology: A Multi-Scale Approach
Quantum Mechanical Calculations
Using density functional theory (DFT) to model electronic structures at the atomic level and predict how different elemental compositions would affect material properties.
Molecular Dynamics Simulations
Studying how these materials behave at slightly larger scales and under different environmental conditions, particularly important for understanding stability issues.
Property Prediction
Combining these approaches to predict key performance metrics including band gap, charge carrier mobility, and thermal stability.

Results and Analysis: Unlocking Perovskite Potential
The computational work provided crucial insights into why certain perovskite formulations performed better than others. Researchers identified specific crystal structures and elemental combinations that offered optimal electronic properties while maintaining better stability—a known weakness of early perovskite solar cells.
The simulations revealed how different organic cations incorporated into the perovskite lattice affected the material's tolerance to defects, helping explain why some formulations maintained high efficiency even with relatively inexpensive processing methods. This understanding directly informed experimental efforts to develop more robust perovskite solar cells.
The Scientist's Toolkit: Essential Resources for Computational Materials Chemistry
The MCC provided researchers with a sophisticated suite of computational tools and resources. While wet labs require beakers and Bunsen burners, the computational chemist's toolkit looks quite different:
| Tool/Resource | Function | Real-World Analogy |
|---|---|---|
| High-Performance Computing Clusters | Provides the processing power needed for complex quantum calculations | The laboratory space where experiments are conducted |
| Density Functional Theory (DFT) Codes | Software that solves quantum mechanical equations to predict electronic structure | The microscope that reveals atomic-scale structure |
