6 FAQs about [The prospects of nanocrystalline solar cells]
What is a nanocrystalline solar cell?
The new nanocrystalline solar cell achieves for the first time the separation of light absorption and charge carrier transport rendering its production costs at least five times lower than that of conventional silicon based devices. The production methods are very simple, and components of the cell are available at a low cost.
Is a new generation of photovoltaic cells based on nanocrystalline materials?
Until now, photovoltaics — the conversion of sunlight to electrical power — has been dominated by solid-state junction devices, often made of silicon. But this dominance is now being challenged by the emergence of a new generation of photovoltaic cells, based, for example, on nanocrystalline materials and conducting polymer films.
How does nanocrystalline silicon differ from Silicon nanocrystal?
In addition, nanocrystalline silicon also differs from the silicon nanocrystal material that consists of small nanocrystals (typically <5 nm) demonstrating quantum effects (see Chaps. 24, “Nanocrystalline Silicon-Based Multilayers and Solar Cells” and 26, “Colloidal Silicon Quantum Dots and Solar Cells” ).
How much photovoltage can nanocrystalline cells produce?
In the conventional picture, the photovoltage of photoelectrochemical cells does not exceed the potential drop in the space-charge layer (Box 1 Figure). But nanocrystalline cells can develop photovoltages close to 1 V even though the junction potential is in the millivolt range.
Can nanocrystalline photovoltaic cells be used to convert solar energy into electricity?
Conventional photovoltaic cells for solar energy conversion into electricity are solid state devices do not economically compete for base load utility electricity production. The low cost and ease of production of the new nanocrystalline cell should be benefit large scale applications in particular in underdeveloped or developing countries.
What is new in nanocrystalline materials?
The phenomenal recent progress in fabricating and characterizing nanocrystalline materials has opened up whole new vistas of opportunity. Contrary to expectation, some of the new devices have strikingly high conversion efficiencies, which compete with those of conventional devices.
