    • A photovoltaic element having an electrode structure having joining portions (A) in which collecting electrodes are spacedly arranged on a light receiving face side of the photovoltaic element such that they are individually joined to a bus bar electrode. Each of the joining portions (A) has a first joining portion (i) having a first paste. Each of collecting electrodes (b) excluding the collecting electrodes (a) positioned at opposite end sides of the arrangement of the collecting electrodes further has a second joining portion (ii) having a second paste with a smaller resistivity than that of the first paste. A proportion of the first joining portion (i) in the joining portion (A) of each of the collecting electrodes (a) is greater than a proportion of the first joining portion (i) in the joining portion (A) of each of the collecting electrodes (b). A process for the production of the photovoltaic element.
    • 一种具有电极结构的光电元件,具有接合部分(A),其中收集电极间隔地设置在光电元件的光接收面侧,使得它们分别接合到母线电极。 每个接合部分(A)具有具有第一浆料的第一接合部分(i)。 除了位于集电电极的配置的相对端侧的集电极(a)之外的每个集电极(b)还具有第二接合部分(ii),其具有比第一浆料的电阻率小的第二焊膏。 每个集电电极(a)的接合部分(A)中的第一接合部分(i)的比例大于第一接合部分(i)在接合部分(A)中的比例 收集电极(b)。 一种用于生产光伏元件的方法。
