New Capabilities

Manganese outperforms precious metals for CO₂ conversion; perovskite-silicon tandems reach commercial production

February 9th, 2026: Combined Advances Signal Broader Energy Materials Shift

Overview

Two breakthroughs in energy materials are making cleaner power more practical. Yale and University of Missouri researchers showed manganese converts CO₂ into formate, outperforming precious-metal catalysts that cost thousands of times more, while perovskite-silicon tandem solar cells crossed 34% efficiency in commercial production.

These advances replace expensive, scarce materials with cheaper alternatives. Formate from CO₂ supplies hydrogen for fuel cells, and perovskite tandem cells that capture more spectrum generate roughly 20% more power per panel. Oxford PV shipped its first commercial modules in 2024, and Hanwha QCells plans mass production in 2027.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

April 1954

Bell Labs Silicon Solar Cell (1954)

Scientists Calvin Fuller, Daryl Chapin, and Gerald Pearson at Bell Telephone Laboratories demonstrated the first practical silicon solar cell, converting 6% of sunlight to electricity. Previous selenium cells managed less than 1%. Bell announced the invention on April 25, 1954, calling it a possible source of unlimited power from the sun.

Then

The technology was too expensive for consumer use, costing about $300 per watt. Early applications focused on spacecraft, where cost mattered less than weight and reliability.

Now

Silicon photovoltaics became the dominant solar technology. By 2025, costs had dropped to around $0.20 per watt and efficiency approached the theoretical limit, driving the search for tandem architectures.

Why this matters now

The 6% efficiency of 1954 established the baseline that tandem cells have now multiplied nearly sixfold. Each efficiency breakthrough compounds the economic case for solar power.

1961

The Shockley-Queisser Limit (1961)

William Shockley and Hans-Joachim Queisser calculated that single-junction solar cells cannot exceed approximately 33% efficiency due to fundamental thermodynamic constraints. Photons below the bandgap pass through unused; photons above it waste excess energy as heat. This limit became the theoretical ceiling for silicon technology.

Then

The calculation redirected research toward multi-junction cells that could capture different portions of the solar spectrum with different materials.

Now

The limit held as an apparent ceiling for commercial silicon cells for over 60 years. Only tandem architectures—adding a perovskite layer to capture high-energy photons—have decisively broken through.

Why this matters now

LONGi's 34.85% tandem cell exceeds the Shockley-Queisser limit by nearly 2 percentage points. This represents not just incremental improvement but a fundamental shift in what silicon-based solar can achieve.

2000-present

Platinum Catalyst Replacement in Fuel Cells (2000s-present)

Fuel cell development was long constrained by reliance on platinum catalysts, which cost over $30,000 per ounce and faced supply limitations. Researchers pursued alternatives using iron, cobalt, and nickel with varying success. The challenge was matching platinum's catalytic activity and durability with earth-abundant materials.

Then

Some alternatives achieved comparable initial performance but degraded rapidly, limiting practical applications.

Now

Improved understanding of catalyst design—particularly ligand modifications and atomic-level engineering—gradually closed the performance gap. Non-precious-metal catalysts now serve in some commercial fuel cell applications.

Why this matters now

The Yale-Missouri manganese catalyst follows this trajectory, achieving superior performance through clever molecular design rather than expensive materials. The ligand modification approach could transfer to other catalyst challenges.
