Inorganic and Organic Photovoltaics

In spite of the high level of commercial success of inorganic semi-conductor based photovoltaic cells, they are unlikely to challenge seriously electricity generation from fossil fuels because they are costly to manufacture and it is also difficult to make large area cells. These difficulties have spurred on research into organic alternatives, especially those that can be incorporated into or be part of a polymer, thus making cell construction easier. 

It is regarded as early days in this field of molecnlar photovoltaics and cerfainly mnch too early to say if these approaches will in the end provide viable commercial prodncts.
