Definitions
- the present invention relates to a solar cell module and a solar power generation device.
- a solar energy converter described in Patent Document 1 is known as a solar power generation device that generates power by installing solar cells on the end face of a light collector and making light propagated through the light collector enter the solar cells. It has been.
- This solar energy converter generates electricity by causing a phosphor to emit light by sunlight incident on the light collector and propagating the fluorescence emitted from the phosphor to solar cells installed on the end face of the light collector. Yes.
- the present invention has been made to solve the above-described problem, and a solar battery module capable of efficiently taking light into a solar battery cell via a light collector and a solar power generation apparatus using the solar battery module The purpose is to provide.
- a solar cell module includes a light collector that allows light from the outside to enter from the first main surface, propagate inside, and exit from the end surface, and the light collector A solar cell that receives the light emitted from the end surface and generates electric power, and an alignment mark corresponding to at least one of the light collector and the solar cell, and the alignment
- the solar battery cell and the light collector are installed in a state of being aligned with each other with reference to a mark.
- the alignment mark includes a first alignment mark corresponding to the light collector and a second alignment mark corresponding to the solar cell,
- the solar battery cell and the light collector are installed in a state of being aligned with each other with the first alignment mark and the second alignment mark as a reference.
- the first alignment mark has a reflection characteristic for reflecting the light.
