TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Structure: The hybrid organic solar cell has the general structure: Substrate + EM/HTM/dye/SOL/EM; Substrate + EM/SOL/dye/HTM/EM; or Substrate + EM/HTM/SOL/EM, where EM is an electrode material (which is a transparent conductive oxide (TCO) and metal, with at least one of the EM layer(s) of the cell is a TCO), HTM is a hole transport material, dye is a suited dye (comprising vapor-deposition of the SOL of the hybrid organic solar cell). Preferred Component: The flexible substrate is a glass, coated glass, polymeric foils, like foils (made from polyethylene terephthalate (PET), polyethylene naphthalene (PEN) or polyimide (PI)), norbornene-based foils, tin (IV) oxide (SnO2)-coated metal foils or stainless steel foils.Preferred Method: The SOL is vapor-deposited. Second layer(s) of the hybrid solar cell is vapor-deposited in addition to the SOL. The method includes depositing and/or vapor-depositing an additional layer of lithium fluoride close to the EM interfaces either on one side or both sides and increasing the surfaces of the interfaces of the layers by using structured ITO, co-evaporation of HTM and dye and/or dye/titanium (IV) dioxide (TiO2) or co-evaporation of HTM and a dopant. The dye is deposited in a thickness of 5-65 nm. The SOL is deposited in a thickness of 5-50 nm. More than one dye is used in one cell. The substance of the HTM is doped.Preferred Properties: The additional layer has a thickness of 0.1-50A. The flexible hybrid organic solar cell has a complete cell thickness of 100 nm, and an efficiency of 0.7-1.3% measured at 60 mW/cm2.
