SERIES CONNECTION SOLAR CELL AND SOLAR CELL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a hetero-cell multi-connection solar cell which can reduce light reflection loss, and a solar cell system using the same which has high conversion efficiency.

SOLUTION: The series connection solar cell comprises a plurality of solar cell units which are connected electrically in series without stacking and each have a different absorption wavelength range, and light guide means to guide light incident from the outside to generate power by irradiating each of the plurality of solar cell units with light in the absorption wavelength range.
