Producing layered structures with semiconductive regions or subregions

A method comprising:

• producing a layered structure that includes:
• a set of semiconductive regions including:
• one or more channel regions;
• and
• one or more light-interactive regions;
• the act of producing the layered structure comprising:
• producing a first one of the channel regions and a first one of the light-interactive regions from the same semiconductive polymer material as a substantially continuous layer and producing a contacting electrode in charge-flow contact with the first light-interactive region and electrically connected to the first channel region so that, when conductive, the first channel region provides an electrical connection between the contacting electrode and other circuitry.

A light-interactive device comprising:

• a layered structure that includes:
• an array with two or more cell regions, one or more of the cell regions each including a respective set of semiconductive subregions;
• each cell region's set of semiconductive subregions including:
• one or more respective channel subregions;
• and
• one or more respective light-interactive subregions;
• each of a set of one or more of the cell regions further including a respective cell electrode subregion that is in charge-flow contact with a first one of the cell region's light-interactive subregions;
• when conductive, the cell region's first channel subregion providing an electrical connection between the respective cell electrode subregion and other circuitry;
• the first channel subregion and the first light-interactive subregion including the same semiconductive polymer material as a substantially continuous layer.

A method comprising:

• a set of semiconductive regions including:
• one or more channel regions;
• and
• one or more light-interactive regions;
• the act of producing the layered structure comprising:
• producing a contacting electrode;
• and
• over the contacting electrode, printing and forming a first one of the channel regions and a first one of the light-interactive regions as a same continuous layer of semiconductive polymer material;
• the contacting electrode being in charge-flow contact with the first light-interactive region and electrically connected to the first channel region so that, when conductive, the first channel region provides an electrical connection between the contacting electrode and other circuitry.

A layered structure comprising:

• a contacting electrode layer;
• a layer of semiconductive polymer material over the contacting electrode layer;
• the layer of semiconductive polymer material being continuous over the contacting electrode layer and including:
• a channel region;
• and
• a light-interactive region that is operative as a charge generation layer;
• the contacting electrode layer being in charge-flow contact with a first side of the light-interactive region;
• when conductive, the channel region providing an electrical connection between the contacting electrode layer and other circuitry;
• a charge transport layer over the layer of semiconductive polymer material;
• charge transport layer including a conductive polymer material or organic material;
• and
• a top electrode layer over the charge transport layer;
• the charge transport layer being operative to transport charge carriers from the light-interactive region toward the top electrode layer in response to an electric field between the contacting electrode layer and the top electrode layer.
