The Mini-Modul

To achieve the project specifications, individual subcells are connected in series on the substrate.

Module in adapter PCB

For characterization of all subcells, the module is installed in the adapter PCB. Here: in an inert atmosphere.

Reference measurements for indoor illumination

Preparations for measuring the solar cells under indoor illumination (400 lux and without infrared component).

Adapter PCB with spring contacts

For the electrical contacting of the solar cell, small spring contacts are soldered onto the PCB.

Cross-sectional analysis

Preparation of the solar cells for cross-sectional analysis of the layers in the scanning electron microscope.

Light dependent behavior

The intensity of the illumination can influence the solar cell characteristics. This is investigated with the aid of filters.

The Project’s Overview

The acronym FOXES stands for the project title “Fully Oxide-based Zero-Emission and Protable Energy Supply“. Within this EU-project we develop in collaboration with our project partners

a device of approx. 20x20mm² lateral dimension, which powers itself via room illumination. The gained energy is then used to take measurements of air quality and to transfer these data wirelessly.

Contribution of the University Wuppertal

The Chair of Electronic Devices provides it's expertise in thin film solar cells and researches within this project a lead-free solar cell that delivers a voltage of four volt under usual room illumination (ca. 400 lux). The efficiency has to be minumum ten percent, wich translates to six micor watts per square centimeter.
