Abstract：To overcome the low precision problem of the existing engineering mathematical model for silicon solar cell, an improved non-linear engineering simplified mathematical model for silicon solar cell was proposed based on the theoretical model. The influences of some subordination factors were neglected, and only four electrical parameters （i. e. the short-circuit current Ise-ref, the open-circuit voltage Uoc-ref, the current of maximum power point Im-ref and the voltage of maximum power point Um-ref） under standard test conditions were used. These parameters were provided by manufacturers. More importantly, the influences of series resistance in arbitrary solar radiation and cell temperature were firstly taken into account to improve the accuracy. Experiments of output characteristic for solar cell were compared with the simulation by the simplification model. The results show that the model error is under 6 percent, and its accuracy is acceptable for most practical engineering cases.
