"solution printing strategy for meniscus-assisted-coating (MAC)...  more ordered molecular packing and better nanofiber interpenetrating network structure for active layer prepared by MAC... extended the MAC method to the preparation of 1×1 cm2 devices with power conversion efficiency (PCE) over 12 percent. Various active layer films with PCE>15 percent are also prepared"
