Photovoltaics: Dye Sensitized Solar Cells

4 Feb 2015

A solar cell or photovoltaic cell is a device that converts light energy into electrical energy. Dye-sensitized solar cells (DSC) are currently subject of intense research in the framework of renewable energies as a low-cost photovoltaic (PV) device. Electricity generated from a PV produces zero emissions, is modular, and can produce energy anywhere the sun shines. This application note illustrates the use of the Autolab PGSTAT302N in combination with the Autolab LED Driver kit to perform DC characterization of a PV device.

Autolab PGSTAT302N

Metrohm AG

This modular high current potentiostat/ galvanostat, with a compliance voltage of 30 V and a bandwidth of over 1 MHz, combined with our FRA2 module, is specially designed for electrochemical impedance spectroscopy. The PGSTAT302N is the succesor of the popular PGSTAT30. The maximum current is 2 A, the current range can be extended to 20 A with the BOOSTER20A, the current resolution is 30 fA at a current range of 10 nA. With a special modification, the PGSTAT302N also offers the possibility to perform Dynamic iR compensation.

Atomic Absorption / Emission SpectroscopyAtomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) — also called optical emission spectroscopy (OES) — are used to detect the elemental constituents in samples. Both techniques involve the atomization of a sample. Atomic absorption spectrometers may use a flame or furnace to create an atomic vapor of the sample before irradiation with spectral light. Optical emission spectrometers may use a flame, inductively coupled plasma (ICP), microwave plasma (MP) or spark arcs to atomize and excite the sample. At higher excitation energies, electrons can be emitted instead of photons, which can be useful for samples that can’t be atomized and for surface analysis. Explore electron spectroscopy equipment such as Auger spectrometers and photoelectron spectrometers for surface elemental analysis of samples.
