Excerpt: A dye-sensitized solar cell (DSSC, DSC or DYSC) is a relatively new class of low-cost solar cell, that belong to the group of thin film solar cells. It is based on a semiconductor formed between a photo-sensitized anode and an electrolyte, a photoelectrochemical system. This cell was invented by Michael Gr tzel and Brian O'Regan at the cole Polytechnique F d rale de Lausanne in 1991 and are also known as Gr tzel cells. This cell is extremely promising because it is made of low-cost materials and does not need elaborate apparatus to manufacture. In bulk it should be significantly less expensive than older solid-state cell designs. It can be engineered into flexible sheets and is mechanically robust, requiring no protection from minor events like hail or tree strikes. Although its conversion efficiency is less than the best thin-film cells, its price/performance ratio (kWh/(m annum dollar)) should be high enough to allow them to compete with fossil fuel electrical generation (grid parity). Commercial applications, which were held up due to chemical stability problems, are now forecast in the European Union Photovoltaic Roadmap to be a potentially significant contributor to renewable electricity generation by 2020. In a traditional solid-state semiconductor, a solar cell is made from two doped crystals, one doped with n-type impurities (n-type semiconductor), which has extra free electrons, and the other doped with p type impurities (p-type semiconductor), which is lacking free elect...More: http: //booksllc.net/?id=1932063
