In a landmark achievement for green energy innovation, scientists have doubled the power conversion efficiency (PCE) of all-organic solar cells using a revolutionary electrode fabrication method that preserves delicate film layers. This promising development, led by Associate Professor Masahiro Nakano of Kanazawa University in collaboration with REIKO Co., Ltd. and Queen's University (Canada), could reshape the future of clean solar technologies.

Why All-Organic Solar Cells Matter

The need for eco-friendly alternatives to silicon and perovskite solar cells has never been greater. While silicon panels dominate today's market, their production and disposal involve hazardous substances. Perovskite solar cells, despite their higher efficiencies, often contain toxic materials such as lead.

All-organic solar cells, built entirely from carbon-based materials, offer a compelling solution:

  • No hazardous metals

  • Safe and inexpensive disposal

  • Flexible, lightweight design

  • Reduced environmental footprint

Despite these advantages, the biggest barrier has been efficiency. Until recently, all-organic solar cells topped out at around 4% PCE — far below silicon (>27%) and perovskite (>26%) cells. That is, until now.


The Double Efficiency Breakthrough

The research team tackled two fundamental technical hurdles:

1. Transparent Organic Electrodes Without Harsh Processing

Traditionally, fabricating highly conductive organic electrodes required high temperatures or strong chemicals — not ideal for delicate organic films. The team developed a new transparent electrode using PEDOT:PSS, which can be processed at only 80°C and achieves excellent conductivity (sheet resistance: <70 Ω/sq).

2. Gentle Layering via Lamination

Next, they innovated a lamination method for carbon nanotube electrodes, allowing separate preparation and then precise layering onto the solar cell. This prevented damage to underlying organic films, a common issue with solution-based methods.

By combining these two innovations, the team achieved a record PCE of 8.7% for all-organic solar cells — more than double the previous state-of-the-art.


What This Means for the Future

This breakthrough opens doors for practical deployment of all-organic solar cells in:

  • Agricultural fields where toxicity is a concern

  • Wearable electronics requiring lightweight, flexible power sources

  • Urban installations on surfaces unsuited for rigid panels

The technology is not just cleaner; it's smarter, adaptable, and potentially scalable. And with ongoing efforts to further improve electrode conductivity, we may see even higher efficiencies soon.


A Step Toward Sustainable Innovation

This success reflects a broader trend in materials science: integrating green chemistry principles into high-performance technologies. The team’s work, published in Advanced Functional Materials, is a pivotal example of eco-conscious design paired with cutting-edge research.

"We believe this achievement significantly contributes to the practical application of environmentally friendly solar cells," said the team in their publication.
