Abstract: A solar cell includes a first substrate, a first hole transport layer, a first photoelectric conversion layer containing a perovskite compound, and a second photoelectric conversion layer containing a photoelectric conversion material in this order. A band gap of the perovskite compound is greater than a band gap of the photoelectric conversion material. With respect to an absorption wavelength of the first photoelectric conversion layer 3, a refractive index nA of the first hole transport layer 2 satisfies refractive index of the first substrate≤nA≤refractive index of the first photoelectric conversion layer. Further, with respect to a transmission wavelength of the first photoelectric conversion layer 3 and an absorption wavelength of the second photoelectric conversion layer 5, a refractive index nB of the first hole transport layer 2 satisfies refractive index of the first substrate≤nB≤refractive index of the first photoelectric conversion layer.

Abstract: A plant cultivation apparatus of the present disclosure includes a first light source unit configured to include a first laser diode radiating a first light beam, and a first scanning mechanism scanning the first light beam and forming a first radiation region, a second light source unit configured to include a second laser diode radiating a second light beam, and a second scanning mechanism scanning the second light beam and forming a second radiation region, and a signal processor configured to control the first light source unit and the second light source unit. A wavelength of the first light beam is the same as a wavelength of the second light beam. The signal processor forms a multiple radiation region by causing the first radiation region and the second radiation region to overlap each other.
