Examples
Example Embodiment
[0016] Example 1.
[0017] (1) Place the PERC polycrystalline silicon solar cell on the heater and heat the heater to 175°C, then apply a forward voltage of 1V to the polycrystalline silicon solar cell for 10 minutes, and then take the polycrystalline silicon solar cell out of the heater.
[0018] (2) Heat the heater to 400°C, place the polysilicon solar cell on the heater again, apply a reverse voltage of 0.3V to the polysilicon solar cell for 1 minute, and then take the polysilicon solar cell out of the heater.
[0019] The control sample is a PERC polysilicon solar cell without any treatment.
[0020] figure 1 It is the voltage change of the light decay of the polycrystalline silicon PERC solar cell after the treatment in Example 1 and the untreated polycrystalline silicon PERC solar cell;
[0021] figure 2 The light decay efficiency change of the polycrystalline silicon PERC solar cell after the treatment in Example 1 and the untreated polysilicon PERC solar cell in the control sa...
Example Embodiment
[0022] Example 2.
[0023] Others are the same as in Embodiment 1. The applied forward voltages are 2V and 4V respectively, which can reduce the degree of light decay to less than 1.5% and less than 1%, respectively.
Example Embodiment
[0024] Example 3.
[0025] Others are the same as in Example 1. In step 1, the heater is heated to 150°C and 250°C respectively, and both can reduce the degree of light decay to less than 1%.
