摘要： The present invention relates to the charge control of the front and back passivation layers of a solar cell, which allows a common passivation material to be used on both the front and back surfaces of a solar cell. A solar cell according to one embodiment of the present invention comprises an emitter and a base. The cell further includes a first passivation layer adjacent the emitter, the first passivation layer having a charge. The cell also includes a second passivation layer adjacent the base, the second passivation layer having a charge opposite to the charge of the first passivation layer, wherein the first passivation layer and the second passivation layer include a common passivation material. The first and second passivation layers can include any suitable dielectric material capable of holding either a positive or a negative charge, and each of the first and second passivation layers can be charged at any suitable point during manufacture of the cell, including during or after deposition of the passivation layer(s).
摘要翻译：本发明涉及太阳能电池的正面和背面钝化层的电荷控制，其允许在太阳能电池的正面和背面两者上使用普通的钝化材料。根据本发明的一个实施例的太阳能电池包括发射器和基座。该单元还包括与发射极相邻的第一钝化层，第一钝化层具有电荷。所述单元还包括与所述基底相邻的第二钝化层，所述第二钝化层具有与所述第一钝化层的电荷相反的电荷，其中所述第一钝化层和所述第二钝化层包括共同的钝化材料。第一钝化层和第二钝化层可以包括能够保持正电荷或负电荷的任何合适的电介质材料，并且第一钝化层和第二钝化层中的每一个可以在电池的制造期间的任何合适的点处被充电，包括沉积期间或之后的钝化层。
