Flexible semitransparent organic photovoltaic (OPV) modules are thin paperflexible. The layers of OPV are fabricated by solution-coating under ambient airroom-temperature environment. We developed an Lab-to-Fab technique for upscaling the cell to large-area module. The design of transparent electrode enables the high-transparency of module. The new low-cost encapsulation technique highly improves the lifetime of module. The performance is examined under outdoor greenhouse test.

Our breakthrough: Novellow-cost encapsulation technique for flexible module. Our flexible module has power conversion efficiency (PCE) of 6~8average visible transmittance (AVT) of 17. The PCE is higher than that reported in the world based on the slot-die coated module with the same area. The T80 lifetime under outdoor greenhouse test is more than 200 days compared to the currently reported data of 90 days.

1) Solar panel: Thinlight OPV module can be easily installed on large-area wallswindows of building for facilitating BIPV. (2) Carbon reduction: Energy payback time of Si PV is ten times larger than that of OPV. (3) Energy saving: serve as energy-saving films.(4) Indoor energy harvest: OPV module under indoor lighting has high PCE, providing energy for the sensors of IOT.(5) Smart, wearableflexible electronic: serve as self-power source to replace the conventional battery.
