TECHNOLOGY FOCUS - ELECTRONICS - Preferred Components: In the element module: the photoelectric conversion element has a light incident side and a rear side opposed to the light incident side and the anchoring layer anchors the rear side; a hollow layer (6) is formed between the photoelectric conversion element and the other of the base materials; the hollow layer is in a dry air, inert gas or vacuum atmosphere; the photoelectric conversion element is in close contact with the other base material; at least one of the two base materials have at least one of selective wavelength absorption, selective wavelength reflection, anti-staining, anti-reflection, diffusion or hard-coating function; the sealing portion is provided on the peripheral portion of the incident side, rear side or lateral side of the photoelectric conversion element; the two base materials are glass plates; the anchoring layer contains at least one adhesive that comprises thermoplastic, thermosetting, room-temperature-setting or energy ray-setting adhesives; the energy ray-setting adhesive is an UV-setting adhesive; a support is provided on the peripheral portion of the incident side of the photoelectric conversion element; optical diffusion fine particles are provided on the light incident side of the photoelectric conversion element; and the anchoring layer lies between the photoelectric conversion element and one of the base material and elastic modulus of the anchoring layer is less than or equal to 500 MPa. The photoelectric conversion element includes a transparent base material, an opposed base material and a power generating element section, where the sealing portion is provided between the peripheral portions of the transparent and opposed base materials.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The module further comprises: a sealant provided between the peripheral portions of the two base materials; shielding material provided between the peripheral portions of the two base materials to suppress the entry of moisture; the support provided between the photoelectric conversion element and the other of the base materials; and the optical diffusion fine particles provided between the photoelectric conversion element and the other of the base materials.
