METHOD OF MANUFACTURE FOR A PARTIALLY-SPRAYED LAYER ORGANIC SOLAR PHOTOVOLTAIC CELL

摘要

The fabrication and characterization of large scale inverted organic solar array fabricated using all-spray process is disclosed. Solar illumination has been demonstrated to improve transparent solar photovoltaic devices. The technology using SAM has potential to revolute current silicon-based photovoltaic technology by providing a complete solution processable manufacturing process. The semi-transparent property 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. This significantly expands their use in indoor applications. Additionally, these modules can be integrated into soft fabric substances such as tents, military back-packs or combat uniforms, providing a highly portable renewable power supply for deployed military forces.
