Abstract: PROBLEM TO BE SOLVED: To simplify optical axis alignment and manufacturing process steps by performing patterning of the lens shape of a second microlens array by utilizing a first microlens array. SOLUTION: The patterning of the lens shape of the second microlens array is performed by irradiating the first microlens array with UV parallel light beams. The UV parallel light beams are condensed by the respective lenses of the first microlens array and expose the resist layers applied on the focal planes of the lenses. The points to be exposed can be changed by changing the incident angles of the UV parallel light beams and the resist patterns of the desired shapes can be obtained by controlling the incident angles of the UV parallel light beams and the exposure time. The shapes of the resist patterns are thereafter transferred to intermediate glass layers and the recessed parts are filled with a UV curing resin of a high refractive index by performing etching.

Abstract: PROBLEM TO BE SOLVED: To provide a solar cell module which can raise light condensing efficiency by lowering the reflectivity on the surface of the solar battery so as to take in sunlight sufficiently. SOLUTION: The solar cell module includes a solar battery 10, and an optical element 1 arranged at the surface 10a side of the solar battery 10. The optical element 1 includes a lens 2 arranged at the incidence side of sunlight, and a trapezoidal prism 4 arranged at the solar battery 10 side. Furthermore, sunlight is made refracted twice by the light condensing operation of the lens 2 and the refraction operation of the trapezoidal prism 4, so that the incident angle of the sunlight which enters into the surface 10a of the solar battery 10 may be made small. Thus, the light condensing efficiency can be raised since the reflectivity in the surface 10a of the solar battery 10 is lowered, and sunlight can be taken in efficiently.
