Perovskite Tech news
On July 20, 2026, Saule Technologies announced the successful flight test of a long--endurance surveillance drone featuring integrated flexible perovskite solar wings. The prototype, developed in collaboration with the Polish Ministry of Defense, demonstrated a 35% increase in operational flight time compared to standard battery--only configurations. The perovskite cells were applied via a proprietary inkjet printing process directly onto the drone's composite wing structure, allowing for continuous trickle--charging during daylight operations without compromising aerodynamic performance or adding significant weight.
