Abstract
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.
