AI Technical Summary

Technical Problem

Existing two-terminal devices, particularly in optoelectronics, face inefficiencies and high manufacturing costs due to electrical shorts and the need for bypass diodes, which degrade performance and are commercially undesirable.

Method used

A two-terminal device with grooved substrates featuring interdigitated grooves connected in series and parallel, using resistive elements to prevent electrical shorts by preferentially extracting charge at terminals, allowing for efficient and reliable manufacturing.

Benefits of technology

The solution minimizes electrical shorts during manufacturing, enhances device efficiency and reliability, and enables cost-effective production through continuous roll-to-roll processing.

Abstract

To provide a two-terminal device and a method for forming the two-terminal device.SOLUTION: A two-terminal device includes a substrate having a first cell having first a characteristic resistance, a second cell spaced apart from the first cell along a web direction of the substrate and having a second characteristic resistance, first and second terminals formed toward or at opposing edges of the substrate in a lateral direction, each terminal in electrical communication with the first and second cells, and a connection portion between the first and second cells and having third characteristic resistance, the third characteristic resistance is greater than or equal to at least one of the first and second characteristic resistances.SELECTED DRAWING: Figure 17
