Coloring photoactive layer/conductive substrate assembly for coloring photovoltaic cell, has conductive substrate defining contact surface with coloring carrier material and comprising root mean square roughness between specific nanometers

摘要

The assembly (2) has a conductive substrate (8) comprising an electrode coating (12) formed on a substrate (10), where the electrode coating comprises a transparent conductive oxide layer (20) doped with zinc oxide. A coloring photoactive layer (14) comprises a coloring carrier material (16) formed on the conductive substrate, and a coloring (18) presents the carrier material. The conductive substrate defines a contact surface (8A) with the coloring carrier material, where the contact surface of the conductive substrate includes a root mean square roughness between 3 and 10 nanometers. Independent claims are also included for the following: (1) a coloring photovoltaic cell comprising a counter-electrode forming layer formed on a counter-substrate (2) a method for manufacturing a coloring photoactive layer/conductive substrate assembly.
