“…As schematized in Fig. 11 [135], the properties of nanomaterials differ vastly from their bulk counterparts, due to the large ratio of volume to surface area and the phenomenon of quantum confinement [136], [137]. Although several properties of nanomaterials have been known for a few centuries, scientific explanations began to emerge only during the last fifty years.…”

Globally, the cumulative installed photovoltaic (PV) capacity has topped the 100-gigawatt (GW) milestone and is expected to reach 200 GW by the year 2015. More than 90% of the installed PV capacity employs bulk-silicon solar cells. Engineering problems that include thermal and optical challenges have not permitted the large-scale commercialization of concentration PV systems, lack of functional reliabilityand the concomitant lack of economic bankability-being a major barrier. For increasing the efficiency of single-junction cells beyond the Shockley-Queisser limit, several approaches based on concepts such as multiple exciton generation, carrier multiplication, hot-carrier extraction, etc., have been proposed; however, these do not seem to be commercially viable. Since both bulk-silicon and thin-film (amorphous silicon, cadmium telluride, and copper indium gallium selenide) solar cells remain as the only two commercially viable options for terrestrial PV applications, a multi-terminal multi-junction architecture appears promising for inexpensive PV electricity generation with efficiency exceeding the currently feasible 25%. The architecture exploits the present commercial silicon solar cells along with abundant and ultralow-cost materials such as Cu 2 O. With the availability of wellcontrolled manufacturing processes at the sub 2-nm length scale, it will become possible to manufacture ultra-high efficiency and ultra-low cost PV electricity generation modules based on silicon.

“…An examination of the current literature shows that most of these solar cells are based on one-, two-, or three-dimensional structures with nanodimensions (<100 nm). The R&D work related to the nanostructures falls under the buzz word of "nanotechnology" and there are questionable claims on the scientific facts [5]. As an example, the publication of a research paper on multiexciton generation in colloidal silicon nanocrystals [6] motivated the author of [7] to claim that silicon nanocrystals-based solar cells can generate two electrons from one photon, and single junction solar cell efficiencies as high as 40% are possible.…”

We present a comprehensive review on prospects for one-, two-, or three-dimensional nanostructure-based solar cells for manufacturing the future generation of photovoltaic (PV) modules. Reducing heat dissipation and utilizing the unabsorbed part of the solar spectrum are the key driving forces for the development of nanostructure-based solar cells. Unrealistic assumptions involved in theoretical work and the tendency of stretching observed experimental results are the primary reasons why quantum phenomena-based nanostructures solar cells are unlikely to play a significant role in the manufacturing of future generations of PV modules. Similar to the invention of phase shift masks (to beat the conventional diffraction limit of optical lithography) clever design concepts need to be invented to take advantage of quantum-based nanostructures. Silicon-based PV manufacturing will continue to provide sustained growth of the PV industry.
