Dye Sensitized Solar Cells Dssc

Harnessing renewable energy sources is crucial for supporting the energy demands of modern society.

Dye sensitized solar cells dssc. It is based on a semiconductor formed between a photo sensitized anode and an electrolyte a photoelectrochemical system. Dsscs are a promising. Dye sensitized solar cells dsscs are a special kind of a low cost solar photovoltaic cell that efficiently converts visible light into electrical energy. The dye sensitized solar cells dsscs are one of them.

We are recognised as the world leading manufacturer of dye sensitized solar cells through our gcell brand. The dye sensitized solar cell dssc is the newest photovoltaic device configuration. Invented in 1991 by professor michael graetzel and dr. Dye sensitized solar cells dssc by g24 power.

The electron is returned to the dye by an iodine based electron carrier. Dye sensitized solar cells dssc are thin film solar cells based on the photo electrochemical processes. Sunlight kicks out a photon from the dye which travels around an external circuit. Part 1 in a 3 part series on dye solar cells the gamry instruments mobile app is a convenient way to find technical support articles application notes electronic versions of our instrument s user manuals as well as news and events happening in the electrochemical research arena.

In fact in semiconductor p n junction solar cell charge separation is taken care by the junction built in electric field while in dye sensitizes solar cell charge separation is by kinetic competition as in photosynthesis spä th et al 2003. How to build use a dye sensitized solar cell dssc a discussion on energy efficiency. This new class of advanced solar cell can be likened to artificial photosynthesis due to the way in which it mimics natureâ s absorption of light energy. Brian o regan it is given the name because it mimics the photosynthesis process by absorbing natural light.

The modern version of a dye solar cell also known as the grätzel cell was originally co invented in 1988 by brian o regan and michael. A dye sensitized solar cell dssc dsc dysc or grätzel cell is a low cost solar cell belonging to the group of thin film solar cells. The iea calculated that global energy usage increased by 10 from 1990 to 2008 and the number is expected to rise in the coming decades. The dssc comes under the category of thin film solar cells and is able to accomplish a much better efficiency.
