Hybrid solar cell

From Wikipedia, the free encyclopedia

Hybrid photovoltaic cells are a mix of two solar cell technologies.

They comprise dye-sensitized titanium dioxide coated and sintered on a transparent semi-conducting oxide, and a p-type, polymeric conductor, such as PEDOT or PEDOT-TMA, which carries electrons from the counter electrode to the oxidized dye. Since the one polymer replaces the multi-component electrolyte the cells are expected to be far simpler to make reproducibly and should afford the same or similar form factors as the polymer solar cells. This technology, like that of the polymer cell, has not yet advanced to the performance level of that of the dye-sensitized solar cell technology. The efficiency values are in the single digits range. One of the causes of low performance is incomplete filling of the small cavities in the titanium dioxide nanoparticles.
