    • Method for providing at least one contact on a back surface of a solar cell comprising a silicon substrate (2) comprising depositing a passivating layer (3) onto the silicon substrate (2) and thereafter providing at least one contact site and further providing a patterned exposed silicon surface. Then depositing a metal layer (8) and annealing the structure (1) to form metal silicide (9). Thereafter the process involves optionally removing excess metal (8) and finally applying metal onto the silicide (9) to form at least one contact (10). A solar cell comprising a back surface, the back surface comprising a contact, produced by the above mentioned method. A contact (10) for back surface of a solar cell comprising a silicon substrate (2), an amorphous silicon layer (3) deposited onto the silicon substrate (2), a reflective layer (6) with at least one opening (7) deposited onto the amorphous silicon layer (3), in the at least one opening 7 there resides silicide (9), with additional metal covering the silicide (9).
    • 一种用于在包括硅衬底(2)的太阳能电池的背表面上提供至少一个触点的方法,包括在硅衬底(2)上沉积钝化层(3),然后提供至少一个接触位置,并进一步提供图案化 暴露硅表面。 然后沉积金属层(8)并退火结构(1)以形成金属硅化物(9)。 此后,该方法包括任选地除去多余的金属(8),最后将金属施加到硅化物(9)上以形成至少一个触点(10)。 一种太阳能电池,其包括通过上述方法制造的背面,所述背面包括接触部。 一种用于太阳能电池背面的触点(10),包括硅衬底(2),淀积到硅衬底(2)上的非晶硅层(3),具有至少一个开口(7)的反射层(6) 沉积到非晶硅层(3)上,在至少一个开口7中,存在硅化物(9),附加金属覆盖硅化物(9)。
