Flexible Solar Cells: A General Approach for Lab‐to‐Manufacturing Translation on Flexible Organic Solar Cells (Adv. Mater. 41/2019). Issue 41 (9th October 2019) - Meng, Xiangchuan
Abstract : In article number 1903649, Xiaotian Hu, Wei Ma, Yiwang Chen, and co‐workers report a general approach to upscale flexible organic photovoltaics to the module scale without obvious efficiency loss by calculating the shear impulse during the coating/printing process. Photoelectric conversion efficiencies of 9.77% for a 1 cm 2 single chip and 8.90% for a 15 cm 2 solar module are demonstrated. The mechanics of shear impulse link the spin‐coating and slot‐die printing like a small boat overcoming the obstacles of thousands of mountains to arrive at a large‐area printing ferry. This research method also opens up a new strategy of lab‐to‐manufacturing translation for organic optoelectronic devices.
