SOLAR BATTERY, SOLAR BATTERY MODULE AND SOLAR BATTERY SYSTEM

摘要

Disclosed are a solar battery and a solar battery module with which the amount of electrode material used is small and the manufacturing yield is good. The solar battery is provided with a first main surface side electrode (40) and a second main surface side electrode (41). The first main face side electrode (40) has a plurality of fine wire-shaped electrodes (40a) and connection electrodes (40b) which are electrically connected to the plurality of fine wire-shaped electrodes (40a). The width of the connection electrodes (40b) of the first main face side electrode (40) is smaller than the width of the connection member used for solar battery connection. The second main face side electrode (41) has a plurality of fine wire-shaped electrodes (41a) and connection electrodes (41b) which are electrically connected to the plurality of fine wire-shaped electrodes (41a). The width of the connection electrodes (41b) of the second main face side electrode (41) is larger than the region width (W) of the connection electrodes (40b) of the first main face side electrode (40).
