Abstract

A tandem photovoltaic structure including, from the rear face to the front face: a first SHJ solar cell comprising a first layer of P-type doped amorphous silicon and a substrate of N-type doped crystalline silicon, a junction layer, a second perovskite-type solar cell comprising an active layer and a second P-type layer, the junction layer being made of N-type TCO and being in direct contact either with the second P-type layer or with the first P-type layer, one amongst the first or second solar cell also comprising an N-type layer, the junction layer serving as an N-type layer in the other one amongst the first or second solar cell.
