Light active sheet and methods for making the same

A method for forming a light-emitting device, comprising the steps of:

• providing a first substrate;
• forming a first conductive surface on the first substrate, the first conductive surface being formed as a conductive pattern comprised of at least one of a conductive coating, a conductive ink and a conductive adhesive;
• forming a pattern of LED chips on the conductive pattern, each LED chip having an anode and a cathode side;
• providing a second substrate;
• forming a second conductive surface on the second substrate;
• fixing the first substrate to the second substrate so that either of the anode and the cathode side of the LED chip is in electrical communication with the first conductive surface and the other of the anode and the cathode side of the LED chips is in electrical communication with the second conductive surface.

A method for forming a light-to-energy device, comprising the steps of:

• providing a first substrate;
• forming a first conductive surface on the first substrate, the first conductive surface being formed as a conductive pattern comprised of at least one of a conductive coating, a conductive ink and a conductive adhesive;
• forming a pattern of semiconductor elements on the conductive pattern, each semiconductor element comprising a charge donor layer side and a charge acceptor side;
• providing a second substrate;
• forming a second conductive surface on the second substrate;
• fixing the first substrate to the second substrate so that either of the charge donor and the charge acceptor side of the semiconductor elements is in electrical communication with the first conductive surface and the other of the charge donor and the charge acceptor side of the semiconductor elements is in electrical communication with the second conductive surface.
