Measurements and Simulations on the Mechanisms of Efficiency Losses in HIT Solar Cells

Figure 5

Horizontal cutline of the electrostatic potential profile at amorphous/crystalline heterojunction in HIT and at junction level for reference solar cell. Both cells are at maximum power condition. (a) For sun = 1 and (b) for sun = 100. The metal width is 10 μm and the pitch is 400, 800, and 1600 μm.
