Dyenamo toolbox for investigation of complete DSSC devices
This stand-alone piece of equipment has been developed for detailed analysis of small dye-sensitized solar cell devices with an active area of 1cm2 or less.
The standard light source is a white light-intensity light emitting diode (LED). The maximum light intensity is 1 sun equivalent (1 sun = 1000 W m-2 AM1.5G).
The Dyenamo toolbox is designed for small-modulation transient measurements for rapid determination of electron lifetimes and electron transport times in DSSC devices. Furthermore, electron accumulation in the mesoporous electrode of the DSSC can be determined by charge extraction measurements. Finally, standard IV-curves can be recorded at different light intensities.
Analytical techniques included:
- JSC vs Light intensity
- VOC vs Light intensity
- Current - voltage curves (at different light intensities and in the dark)
- Electron transport time under short-circuit conditions
- Electron lifetime under open-circuit conditions
- VOC decay
- Photocurrent transients
- Charge extraction (from short-circuit or open-circuit conditions)
- Additional optional analytical techniques
IMPSE- and IMVS-techniques can be included in the toolbox on demand.
