Abstract
A solar cell and a solar module are provided which have improved output characteristics. A solar cell (20) has a photovoltaic conversion unit (23), a first electrode (21), and a second electrode (22). The first electrode (21) and the second electrode (22) are arranged on one main surface of the photovoltaic conversion unit (23). The first electrode (21) has first finger portions (21a) and a first busbar portion (21b). The first finger portions (21a) extend in one direction. The first finger portions (21a) are connected electrically to the first busbar portion (21b). The width (W11) of the first busbar portion (21b) is smaller than the width (W21) of each first finger portion.
