SOLAR CELLS – DYE-SENSITIZED DEVICES Edited by Leonid A. Kosyachenko .Solar Cells – Dye-Sensitized Devices Edited by Leonid A. Kosyachenko Most solar modules used in photovoltaics are currently produced from crystalline and polycrystalline silicon wafers, the representatives of so-called first generation of solar cells. This type of devices are among the most efficient but at the same time the most expensive since they require the highest purity silicon and involve a lot of stages of complicated processes in their manufacture.
