Scientists use wood to make affordable, dependable, and eco-friendly solar cells

Researchers from Linköping University and the Royal Institute of Technology (KTH) have achieved significant progress in renewable energy technology by creating organic solar cells using untreated kraft lignin derived from wood pulp. Lignin, an abundant organic compound in nature, is harnessed for its potential to produce stable and environmentally friendly solar cells. This breakthrough aims to replace conventional silicon-based solar cells with a sustainable alternative that offers efficiency, reliability, affordability, and environmental friendliness.

The heart of this innovation lies in utilizing wood materials, specifically untreated kraft lignin, contributing to the overall sustainability of organic solar cells. This not only demonstrates a commitment to eco-friendly practices but also positions wood-based solar cells as a promising solution for various applications, especially in large-scale energy supply. The research aligns with the global pursuit of clean energy sources, highlighting the potential of organic solar cells derived from wood materials to play a crucial role in meeting energy needs while minimizing the environmental impact associated with traditional solar technologies.
