Solar Technology at an Inflection Point: CEA Explores Next-Generation Photovoltaics

Silicon-based photovoltaic panels continue to advance, delivering ever-higher efficiencies, but are approaching their theoretical performance limits. In response, France's Alternative Energies and Atomic Energy Commission (CEA) is now spearheading research into next-generation solar technologies, as well as exploring more fundamental, upstream avenues for innovation.

This strategic shift acknowledges that incremental improvements to dominant crystalline silicon cells are nearing a plateau. The CEA's dual-track approach focuses not only on developing immediate successors—such as tandem perovskite-silicon cells or thin-film alternatives—but also on investigating novel materials and physical concepts that could redefine solar energy conversion in the longer term. The goal is to catalyze a new wave of breakthroughs in efficiency, cost, and application versatility beyond the constraints of today's silicon-dominated industry.

​Les panneaux photovoltaïques silicium continuent d’évoluer pour offrir des rendements toujours plus élevés, mais se rapprochent de leurs limites. Le CEA travaille donc sur les prochaines générations et également sur des pistes plus amont.
