Organic conductors for solar cells

Solar cell is one of the most important components in solar energy based equipments as an alternate energy source. Conventional absorption type of collectors are massive and have maintenance problems. Solar cells do the same function of collection very precisely. Conventional solar cells, in general, based on silicon single crystals are MIS or SIS types which have received much attention recently but there is no particular material or combination available which is cheap enough to compete with the large scale fossil-fuel generated electricity.
