Abstract

According to a main objective of the present invention, the three-dimensional arrangement of solar cells is adjusted so as to use sunlight directly coming from the sun mainly for solar power generation while transmitting wavelengths necessary for the growth of plants and reflecting wavelengths unnecessary for or hindering the growth of plants among wavelengths of sunlight passing through the solar cells to use the reflected wavelengths for additional solar power generation.
Sunlight reflected by the dichroic optical filter may be used to additionally generate electricity using solar cells provided perpendicular to the dichroic optical filter, thereby maximizing the use efficiency of sunlight.

First claim

What is claimed is:

1. A solar cell module for a cultivation facility, the solar cell module comprising:
a module case;
dichroic optical filters; and
solar cells connected in a lattice form and inserted into vertical or inclined grooves provided in the module case,
wherein the dichroic optical filters are attached to an underside of the solar cells connected in the lattice form,
wherein the dichroic optical filters are configured to transmit selected wavelengths of sunlight ranging from 400 nm to 500 nm and 640 nm to 700 nm and reflect other wavelengths of sunlight,
wherein the solar cells are configured to generate electricity using sunlight reflected from the dichroic optical filters, and
wherein the solar cells connected in the lattice form are configured to be adjusted in height, width, and spacing therebetween by adjusting an installation angle of the solar cells using the vertical or inclined grooves provided in the module case.
