It has been well known that the density of bulk defects in c-Si substrate, and the density of interface defects ( Dit) on the heterojunction can influence the solar cell performance greatly ( Arafune et al., 2006, Bailey et al., 1996, Kobayashi et al., 2006, Nath et al., 2008 ).
sistivity of silicon wafers has a crucial impact on their performance. This study inves igated the effects of different resistivities on p-TOPCon solar cells. The results indicate that lower resistivity wafers have a higher implied open-circuit voltage (iVoc) value, but higher carrier mobility due to the l
w resistivity leads to an increase in saturation current density (J0). Conversely, solar cells made on higher resistivity silicon wafers have a lower carrier mobility, leading to slower electron-hole recombination and lower bulk recombination, resulting in the advantage of
However, cost considerations need to be taken into account as higher resistivity silicon wafers are more expensive. Therefore, resistivity between 2 - 3 Ω·cm2 is considered the preferred substrate for solar cells as it offers a better balance between cost and achieving high cell efficiency.
In addition, the external reflection of the cell and the light absorption of the front films will not change under the fixed front film and pyramid morphology. For the pyramid angle of 0°, the light absorption inside c-Si substrate is 41.9 mA/cm 2.
The annealing temperature of the solar cell with rear flat surface is fixed at 850 °C. The results in Fig. 4 (a) display that the cell VOC first enhances and then decreases as the pyramid angle increases. The average cell VOC reaches the maximum value of more than 700 mV for the pyramid angle of 12.8°.
