EPFL LPI | IV Lab

GUI program for running IV lab characterization.

The GUI application is broken into two parts: the controller and the interface. The controller handles all the business logic for the application, while the interface handles all the view logic.

Interface

The interface is broken into three major sections

Controller

Base classes

Base classes create a common interface for each component of an IV system.

Hardware Base

A base class for hardware controllers.

Lamp

Defines a common interface for lamp controllers.

SMU

Defines a common interface for source meter units (SMUs) that are used for electrical measurements on the cells.

Computer Parameters

Holds information about the computer such as the data folder location.

IV System Parameters

Holds information about the IV system such as the last calibration date.

System

A system represents an entire IV system and how a user can interact with it. A system consists of a:

• Lamp,
• SMU,
• Computer parameters, and
• IV System parameters

And can define the available measurements.

Result

A base class for measurement results.

Results

Each type of measurement defined by a system has its own type of Result which defines the measurement parameters and output data.

IV Curve Result

Result of an IV curve measurement.

Chronoamperometry Result

Result of a chronoamperometry measurement.

Chronopotentiometry Result

Result of a chronopotentionmetry measurement.

MPP Result

Result of an MPP measurement.
