Introduction

Organic electronic devices are functional stacks. Their performance depends on the sequence, thickness, interfaces, conductivity, optical transparency, surface energy and processing compatibility of every layer.

Device Architecture

Layer order determines carrier flow, optical entry and contact polarity.

Layer Function

Layers may inject, transport, block, generate, emit, sense, gate or protect.

Process Compatibility

Solvents, temperature, roughness and wettability determine fabricability.

Device Families Learning Studio

Organic Solar Cell

Converts absorbed light into collected charges.

OLED

Uses electron–hole recombination to generate light.

OTFT

Uses a gate field to control an organic channel.

Organic Photodetector

Converts light into a detection signal.

OECT

Uses ions to modulate electronic conduction.

Organic Sensor

Detects analytes through electrical or optical change.

Layer-Function Learning

Substrate

Provides mechanical support.

Electrode

Injects or collects charge.

Transport Layer

Moves one carrier type selectively.

Active Layer

Performs absorption, emission, sensing or switching.

Dielectric

Separates gate and semiconductor in a transistor.

Encapsulation

Protects against oxygen, moisture and damage.

Theory and Scientific Background

Layer order and polarity

The stack determines which electrode serves as anode or cathode and which carrier encounters each selective layer.

Thickness effects

Thickness influences resistance, optical transmission, absorption, leakage and reliability.

R = ρL/A     T ≈ e−αL

Fabrication compatibility

A theoretically valid stack can fail when a solvent dissolves an underlying layer, process temperature exceeds substrate limits, or roughness creates pinholes.

Model limitation: This edition performs structural and rule-based checks; it does not solve optical fields, charge transport, electrostatics, mechanical stress or process yield.
