We’re excited to share the latest edition of the Emerging PV Report, now published in Advanced Energy Materials. This annual review compiles and analyzes performance data from over a hundred new studies on emerging photovoltaic (e-PV) technologies, providing the most comprehensive overview of the field to date.

• Perovskite and organic photovoltaics (OPV) continue to lead the way — with certified efficiencies surpassing 26% and 20%, respectively, and clustering around optimal bandgaps (1.37–1.57 eV).
• Tandem and multijunction perovskite devices now consistently exceed 30% efficiency, showing strong open-circuit voltages and fill factors.
• Flexible PVs demonstrate remarkable progress, with flexible perovskite and OPV cells reaching 24% and 18%, alongside improved mechanical and operational stability.
• Semitransparent devices are achieving record light utilization efficiencies (LUE) — up to 5.73% for PSCs and 5.6% for OPVs — paving the way for integration in building and agrivoltaic applications.

However, the report also underscores the need for better standardization and transparency in operational stability testing. Many studies still lack detailed conditions or baseline efficiency values, limiting comparability across technologies.

Overall, this edition highlights a field advancing rapidly in efficiency and functionality, yet still facing challenges in stability, scalability, and reproducibility — key frontiers for the coming years.
