Perovskite Solar Ink SolarInk Achieves Roll-to-Roll Mass Production: Per-Watt Generation Cost Drops to $0.05
Photovoltaic materials company SunRoll completes commissioning of its roll-to-roll printing production line for perovskite solar ink SolarInk, achieving a per-watt generation cost of $0.05 — one-third of traditional silicon solar panels — with first products deployed in off-grid power projects in India and Africa.
Perovskite Solar Ink SolarInk Achieves Roll-to-Roll Mass Production
Photovoltaic materials company SunRoll announced on September 1 the completion of commissioning for its roll-to-roll printing production line for perovskite solar ink SolarInk. The production line prints perovskite photovoltaic thin films onto flexible polymer substrates at a speed of 15 meters per minute, achieving a per-watt generation cost of $0.05 — one-third the cost of traditional silicon solar panels.
SolarInk's photoelectric conversion efficiency is currently 18.5%, lower than monocrystalline silicon's 24%, but its lightweight and flexible characteristics enable applications where traditional silicon panels cannot be used. First shipments have been sent to off-grid power projects in India and Kenya.
