: some of the metals like cadmium used for producing solar PV cells are hazardous and all other materials, except silicon, are not recyclable. Of the total solar PV cells produced in the country, more than 60% is exported.
Another factor grappling the solar photovoltaic industry is the R&D costs. The R&D and engineering costs are rising at a faster rate than integrated circuit (IC) sales, says a report from IC Insights. The R&D and engineering expenditures increased at a CAGR of 12.7% between 1990 and 2007, while semiconductor sales grew at a CAGR of 9.9%.
In the first quarter of 2008, spending on semiconductor R&D grew 12% to $11.1 billion, compared to $10 billion in R&D expenditures in the same period last year. R&D spends, as a percentage of semiconductor market sales were 17.5%, compared to 16.4% in the same quarter last year. According to IC Insights, foundries spent only 7.1% of total sales on R&D and engineering expenditures in Q1 of 2008....
