Disclosed is an apparatus for generating power by amplifying sunlight, including a sunlight amplifying means; and an energy storing means configured to support the sunlight amplifying means and to store an electric energy and a thermal energy generated from the sunlight amplifying means, wherein the sunlight amplifying means includes a first pipe formed of metallic material; a second pipe configured to enclose the first pipe; a solar photovoltaic module installed between the first pipe and the second pipe; and a sunlight amplifying sheet configured with concave mirrors or convex lenses having predetermined shapes and attached to the outer circumference of the second pipe so as to amplify sunlight.

A photovoltaic solar power plant assembly and a method of using said assembly to generate power are disclosed. The assembly includes an array of photovoltaic solar modules arranged in a solar module surface, and an optical structure for redirecting light towards said solar module surface, having a redirected light emitting surface. The optical structure includes: a planar optical waveguide which has a parallel first and second planar waveguide surfaces, wherein the first planar waveguide surface extends parallel to the redirected light emitting surface, wherein the first planar waveguide surface is at least partially covered by a photonic layer which is configured to provide an angular restriction of a light emission from the planar waveguide through the redirected light emitting surface, and a light scattering and/or luminescent material, which material is arranged as particles in the planar optical waveguide and/or in a layer which at least partially covers the second planar waveguide surface.

Disclosed are a solar energy utilization apparatus and a combined structure thereof. The solar energy utilization apparatus comprises a transparent top cover, a reflection groove and a light energy utilization unit. The transparent top cover is provided with a first transparent part recessed inward and a second transparent part protruding upward from the recess of the first transparent part; and based on such structure, sunlight reflected and refracted to the outer side of the transparent top cover can be re-refracted from other regions to the inner side of the transparent top cover, thereby improving the quantity of light refracted into the transparent top cover.
