The photoelectric conversion unit 904 connected in parallel in the photoelectric converter 900 enables the photoelectric converter 900 to reduce the sensitivity to non-uniform illumination and improve its output power under common non-uniform illumination conditions; but its disadvantage is that the photoelectric conversion units connected in parallel The conversion unit 904 has a lower output voltage and a larger output current, which will increase the loss of the output power of the photoelectric converter 900

And a larger output current needs to use a thicker wire to conduct the current, which will increase the cost of the photoelectric converter 900

[0011] However, for non-uniform lighting conditions under specific circumstances, such as lighting with uniform light energy intensity along the first dimension direction and non-uniform light energy intensity along the second dimension direction perpendicular to the first dimension direction, the industry has not yet found Research on photovoltaic power generation by making full use of the non-uniform illumination in this specific situation
