PV characterization


Two axis directional gimbal platform featuring a brushless dc motor direct drive system and magnetic base micromanipulators, almost entirely 3D printed.


Introduction video


Prototype ready!


We are in Milestone 3


The aim of the project is to design and create a system device for optical characterization of thin and transparent materials, as an open source project so it can have a maximum of social impact, and can be utilized and modified by communities around the world. The main application of the device is the measurement of the quantum efficiency (QE) of photovoltaic cells. The device is essentially an automated tilt angle and rotation stage, capable of both tilt angle adjustments (from 0-90 degrees) and for rotation (0-360 degrees) with 1 degree accuracy. There are some additional elements for fixing the sample and for electrical connections.

Short-term goals

Create two working devices. 

Long-term goals

Distribute the device as CC-BY-SA


  1. Design Characteristics
  2. Design
  3. Prototype
  4. Product

See more on the planning



This project is funded
Since the device will be distributed as CC-BY-SA, SENSORICA will have the right to commercialize it. 
You can be co-author in at least a scientific paper describing the device and the process.
