In this paper, a new photovoltaic module was proposed, in which all cells were connected to each other like a fishing net. When any each cell of the whole module got out of order, the photocurrent could flow through the neighbor well-worked cells so that the photovoltaic output loss of the whole module was minimized as much as possible; at the same time, the bad-worked cell could be well protected because only little photocurrent need to flow through the bad-worked cell. Multisim soft was used to simulate the photovoltaic output of the series-circuit module (SM) and fishing-net module (FM) under the various experiment conditions, such as incidental light power, contaminant degree, and area ratio and module dimension (cell numbers in one module). The simulating results show that the FM photovoltaic output is larger in varying degrees than that of the SM under almost all the abovementioned experiment conditions. In the extreme case, here, all cells in one row of the SM and FM were completely bad-worked, the SM photovoltaic out was zero, and the FM one decreases a little. In order to validate the reliability of the simulating results, the real 6 x 6 array SM and FM (36 real cells) were tested and analyzed comparatively under the same experiment condition, such as incidental light power and contaminant degree. The experiment results well according with the simulating ones suggest, again, that the FM photovoltaic output is exactly better than the SM one.
