Abstract

An optoelectronic device includes at least one pixel including an absorption layer made of a first material and arranged on a first face of a first substrate, the absorption layer being intended to convert incident radiation into electrical charges; a lower electrode for collecting the electrical charges; and an upper electrode arranged on the absorption layer; a readout circuit arranged on a second substrate and having at least one readout electrode dedicated to the pixel; the first substrate includes at least one via starting from a second face of the first substrate opposite the first face; the via being electrically connected on the one hand to the lower electrode and on the other hand to at least one hybridization connector for electrically and mechanically coupling the pixel to the readout electrode dedicated to the pixel.

Dependent claims

An optoelectronic device (D1) comprising:

at least one pixel (Pxl) comprising:
an absorption layer (AL) made of perovskite and arranged on a first face of a first substrate (sub1), the absorption layer being intended to convert incident radiation into electrical charges;
a lower electrode (EL1) for collecting the electrical charges;
and an upper electrode (EL2) arranged on the absorption layer (AL);
a readout circuit (ROIC) arranged on a second substrate (sub2) and comprising at least one readout electrode (EL_read) dedicated to the pixel (Pxl);
the first substrate (sub1) comprising at least one via (V1) starting from a second face of the first substrate (sub1) opposite said first face;
said via (V1) being electrically connected on the one hand to the lower electrode (EL1) and on the other hand to at least one hybridization connector (CEM) for electrically and mechanically coupling the pixel (Pxl) to the readout electrode (EL_read) dedicated to said pixel (Pxl).
