NOVELTY - The device (8) comprises a substrate (10), a conversion layer (12) configured for converting radiation into electrical energy, and an intermediate layer arranged between the substrate and the conversion layer and removably adhered to the substrate and to release the conversion layer from the substrate. The substrate and the conversion layer comprise a base layer of molybdenum arranged towards the other of the substrate and the conversion layer, and are present in contact with the intermediate layer. The intermediate layer maintains electrical, chemical and physical properties.    USE - The device is useful for converting incident radiation into electrical energy (claimed), where the device includes a photovoltaic device or cell such as solar panel, nantennas and radiation harvesters.    ADVANTAGE - The device exhibits improved flexibility, lightweight, high light collection yield, and long service life, and can be constructed with removal of toxic components in an economical and environmentally friendly manner.    DETAILED DESCRIPTION - The device (8) comprises a substrate (10), a conversion layer (12) configured for converting radiation into electrical energy, and an intermediate layer arranged between the substrate and the conversion layer and removably adhered to the substrate and to release the conversion layer from the substrate. The substrate and the conversion layer comprise a base layer of molybdenum arranged towards the other of the substrate and the conversion layer, and are present in contact with the intermediate layer. The intermediate layer maintains electrical, chemical and physical properties when bonded between the molybdenum layer and the other of the conversion layer and the substrate. The intermediate layer is degradable by an external influence to release the conversion layer from the substrate. The conversion layer comprises a copper-indium-selenide layer or a copper-indium-gallium-selenide layer, and has electrical, chemical and physical properties associated with the converting of radiation to electrical energy. The intermediate layer comprises metal, which maintains the electrical, chemical and physical properties when bonded between the conversion layer and the substrate, and is dissolvable by acid and base to release the conversion layer from the substrate. The substrate comprises plastic, glass, metal, semiconductor material, and crystalline material. INDEPENDENT CLAIMS are included for:    (1) a method for producing a device for converting radiation into electrical energy;    (2) a method of using a lift-off layer to separate layers of a device for converting radiation into electrical energy; and    (3) a method for disposing a device for converting radiation into electrical energy.
