The present invention refers to a three terminal tandem solar generation unit () comprising: &#x2014;a first absorbing layer () made of a perovskite type compound, &#x2014;a second absorbing layer ('), &#x2014;a first and a second interdigitated front contacts () arranged on the front side of the first absorbing layer (), the first front contact () having a first polarity and the second front contact () having a second polarity, &#x2014;a back contact (&#x2032;) having the first or the second polarity arranged on the back side of the second absorbing layer (&#x2032;), &#x2014;an interface layer (&#x2032;) arranged between the first () and the second (&#x2032;) absorbing layers comprising a first semiconductor sub-layer (&#x2032;) doped according to the first polarity and a second sub-layer (&#x2032;) doped according to the second polarity and configured for enabling carriers associated with a polarity different than the polarity of the back contact (&#x2032;) to be transferred from the second absorbing layer (&#x2032;) to the first absorbing layer () to be collected by the front contact () having a polarity different than the polarity of the back contact (&#x2032;).
