== Understanding the market ==
This Currently the market for solar cells depends on the manufacturing cost, module efficiency cost, and the cost of electricity being the biggest factor for solar cells. The average manufacturing cost for crystalline silicon (1 generation solar cell) is where you can describe what already exists$2.70/Wp, a module efficiency from 12 to 19%, what and it average selling price is needed$3.80Wp. The second generation thin film solar cell, etcsuch as CdTe's manufacturing cost is $0. You may want to include inline references98/Wp and a 10% module efficiency(Hillhouse 250). <ref> You can use The third generation solar cells (CdSe Quantum Dots) are still in the ref code lab phase, but are suppose to include inline referencescost less to manufacture, with a higher module efficiency, and sell at a lower price. See [[Help:Footnotes]] for The first and second generation solar cells have a maximum theoretical conversion efficiency of 31%, whereas the thurd generation's maximum theoretical conversion efficiency is 66%, which is morethan double the effciency (Etgar). When the third generation solar cells like CdSe Quantum Dots Heterojunction solar cells start to be manufactured, they will surpass their predecessors (1st and 2nd generation solar cells) and be the desired solar cells on the market.</ref>
