Mask-stack-shift method to fabricate organic solar array by spray
An all-spray fabrication method for large scale inverted organic solar array is provided. Zinc oxide sol gel solutions and revised layers shorten the fabrication process from 2 days to 5 hours and concurrently improve transparency and visual effect of solar windows, and improve power conversion efficiency over 2× compared to previous devices, due to enhanced device characteristics like increased shunt resistance and fill factor. The method also eliminates human factors such as manual erasing of active layer to make series connections by providing a complete solution processable manufacturing process. The semi-transparency of the solar module allows for applications on windows and windshields. The inventive modules are more efficient than silicon solar cells in artificial light environments, significantly expanding their use in indoor applications. Additionally, these modules can be integrated into soft fabrics such as tents, military back-packs or combat uniforms, providing a highly portable renewable power supply for deployed military forces.
