A photosensitive cell includes an anode and a cathode; a donor-type organic material and an acceptor-type organic material forming a donor-acceptor junction connected between the anode and the cathode; and an exciton blocking layer connected between the acceptor-type organic material of the do nor- acceptor junction and the cathode, the blocking layer consisting essentially of a material that has a hole mobility of at least 10-7 cm2/V-sec or higher, where a HOMO of the blocking layer is higher than or equal to a HOMO of the acceptor-type material.
L'invention concerne une cellule photosensible comprenant une anode et une cathode; un matériau organique du type donneur et un matériau organique du type accepteur formant une jonction donneur-accepteur connectée entre l'anode et la cathode; et une couche de blocage d'excitons connectée entre le matériau organique du type accepteur de la jonction donneur-accepteur et la cathode, ladite couche de blocage étant essentiellement composée d'un matériau doté d'une mobilité de trous d'au moins 10-7 cm2/V-sec ou plus, un HOMO de la couche de blocage étant égal ou supérieur à un HOMO du matériau du type accepteur.
