Title:
CHEMICAL REACTION DEVICE
Document Type and Number:
Japanese Patent JP2023179917
Kind Code:
A
Abstract:
To improve conversion efficiency into a chemical energy of a product material from a solar energy.SOLUTION: In a chemical reaction device, a power is supplied from a PV module 100 to an EC module 102 to generate a chemical reaction by using the power. In the PV module 100, from a light reception surface side, a top cell module in which nt photoelectric conversion cells using a light absorption material of which a band gap is 1.3 eV or more and 1.7 eV or less are series connected and a bottom cell module in which the nb photoelectric conversion cells are series connected by using the light absorption material of which the band gap is 1.0 eV or more and 1.2 eV or less, are stacked and connected in parallel. The EC module 102 is constructed by series connecting nEC EC reactor. nt/nEC is 1.1 or more and nb/nEC is 2 or more.SELECTED DRAWING: Figure 3
