PV characterization

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.

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

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.

The planning is modeled with 2 parallel workflows below. To record your contributions just click on the appropriate box. This will open a new page with the process, where you can record your contributions. You need access to the system to log, ask in the Forum.

R&D workflow: A structured series of technical processes that will move the project from idea to product. See also Conditions workflow below. Work on design, R&D and manufacturing is logged in this section.

Conditions workflow: A structured series of processes that will create the conditions for the project to develop. Work on activities that support product development is logged in this section.

Log non-production work

Definition: Non production work is work that doesn't have a clear deliverable associated with it. Examples are office work, meetings, facilitation, coordination, etc.

Go to the non-production log page (you must be logged in), enter date, activity, and chose PV characterization project. Add short description and a link (if necessary), and press SAVE. You can enter multiple activities before you press SAVE. You can enter multiple activities before you press SAVE. You can modify our logging from My work/My Contributions page.
