One of the most anticipated updates in the field of solar technology has just been released. The new Solar Cell Efficiency Tables (Version 66), authored by Martin A. Green and colleagues, have been officially published in Progress in Photovoltaics. This living document is the global gold standard for reporting the highest independently verified solar cell and module efficiencies—across silicon, perovskite, chalcogenide, organic, and multi-junction categories.

Why These Tables Matter

Since 1993, the efficiency tables have been published every six months to track verified record efficiencies of photovoltaic (PV) devices. But more than a scoreboard, they play a vital role in:

  • Standardizing performance evaluation across global research labs
  • Encouraging independent certification of claims
  • Guiding policy, investment, and industrial innovation

This edition—Version 66—captures the cutting-edge achievements as of May 2025, providing a lens into both current performance benchmarks and future possibilities for solar energy worldwide.

Key Highlights from Version 66

  • 🌞 The highest single-junction silicon cell efficiency now stands at 27.8%, achieved using advanced passivating contact technologies.
  • ⚡ Perovskite solar cells reached an impressive 27.3% in lab-scale tests, demonstrating both high efficiency and rapid development pace.
  • 🌍 The best-performing multi-junction device hit 39.2% efficiency—approaching theoretical limits, used for space and concentrated applications.
  • 🧪 Several new “notable exceptions” were added to include cutting-edge commercial and experimental devices with high stability or new configurations.

Technologies Tracked

The tables track confirmed efficiencies for an impressive array of technologies:

  • Crystalline silicon (PERC, TOPCon, HJT, TBC)
  • Thin-film chalcogenides (CdTe, CIGS, CZTS, etc.)
  • Organic photovoltaics (including tandem designs)
  • Perovskite and perovskite-silicon tandems
  • Multi-junction III-V devices used in aerospace

Each record is backed by independent measurements from globally recognized test labs (NREL, Fraunhofer ISE, ISFH, AIST, etc.) and includes detailed information on area, open-circuit voltage (Voc), short-circuit current (Jsc), fill factor, and more.

What’s New in Version 66?

This version introduces subtle but impactful improvements in classification:

  • 🔍 Clearer distinction between total area, aperture area, and designated illumination area.
  • 📊 Expanded inclusion of EQE and I–V curves for spectral diagnostics.
  • 🧱 Special recognition of commercial modules and “notable exception” formats for real-world relevance.

The Road Ahead: Beyond Efficiency

As solar moves beyond lab efficiencies toward mass deployment, stability, cost, sustainability, and manufacturability will become equally important. However, peak efficiency remains a critical benchmark that informs innovation, market competitiveness, and policy.

The continued rise of perovskites, organic tandems, and multi-junction silicon hybrids suggests the future of solar will be defined not by a single champion, but by diverse solutions optimized for various use cases—from rooftop panels to satellites and wearable devices.

Water Simulations Under Scrutiny: Researchers Confirm Methodological Errors

Image
Accurate water simulations are vital for research in biomolecular structures, drug discovery, and materials science. But a recent study from Oak Ridge National Laboratory (ORNL) has revealed a potential pitfall in long-standing computational methods, raising concerns about the reliability of countless molecular dynamics studies. The Time Step Problem in Simulations At the heart of the issue is the “time step” used in simulations—the small intervals at which calculations are performed. Since the 1970s, scientists have used time steps of 2 femtoseconds (quadrillionths of a second) to simulate molecular motion efficiently. However, the ORNL team has shown that using this standard can introduce significant errors when modeling liquid water, potentially leading to inaccurate predictions of properties such as density, pressure, and hydration energies. “Using longer time steps is tempting because it reduces computational cost,” explained senior scientist Dilip Asthagiri. “But a...

Quantum Chemistry Meets AI: A New Era for Molecular Machine Learning

Image
In a powerful leap forward for computational chemistry and materials design, researchers from Carnegie Mellon University have developed a new kind of molecular machine learning model—one that goes beyond simplistic molecular graphs and integrates fundamental principles of quantum chemistry. Their work, published in Nature Machine Intelligence , could radically enhance our ability to predict chemical behavior, optimize catalysts, and discover new drugs, all while using less data and gaining more scientific insight. The Problem: Traditional Molecular Representations Fall Short Molecular machine learning (ML) models underpin key processes in drug discovery, materials science, and catalysis. However, most existing models use simplified representations such as SMILES strings, 2D graphs, or coordinate matrices. These techniques often lack the quantum-chemical information that governs how molecules truly behave—particularly electron interactions that define reactivity, stability, and...

CrystalGPT: Redefining Crystal Design with AI-Driven Predictions

Image
July 18, 2025 In a major leap for materials chemistry, researchers in the UK have developed Molecular Crystal Representation from Transformers (MCRT) —an AI model likened to ChatGPT for its transformative impact. Dubbed "CrystalGPT" , this foundation model rapidly predicts the physical properties of molecular crystals, revolutionizing how chemists design materials in silico . The AI Revolution in Crystal Design Understanding and predicting the properties of molecular crystals is critical for designing new materials for applications ranging from pharmaceuticals to energy storage. Traditional computational approaches, though powerful, are often resource-intensive and slow. Machine learning methods such as Smooth Overlap of Atomic Positions (SOAP) and atom-centred symmetry functions (ACSFs) have offered improvements, but they struggle with large datasets and subtle structural nuances. CrystalGPT, developed by a team led by Andy Cooper at the University of Liverpool, o...
