Excitonic solar cells, including organic, organic, inorganic and dye-sensitised hybrid (DSC) cells, are promising devices for the conversion of large-scale economic solar energy. The DSC is currently the most efficient and stable exciton photocell. The core of this device is a thick nano-particle film that provides a large surface area for the adsorption of light-collecting molecules. DSC nanoparticles rely on limited electron trapping diffusion, a slow mechanism that may limit the effectiveness of the device, especially at longer wavelengths. The direct electrical pathways provided by the nanowires ensure the rapid collection of carriers generated throughout the device, and a complete Sun efficiency of 3.5% has been demonstrated, limited mainly by the surface area of ​​the nanowire array. We are now expanding our synthetic strategy to design nanowire electrodes with much larger areas available for dye adsorption. It is worth noting that the advantages of nanowire geometry are even more attractive for other types of excitonic photocells, such as inorganic polymers, inorganic compound hybrid devices, in which a continuous, crystalline oriented inorganic phase could be greatly improved the collection of the load.

Thin films of silicon are promising optical absorption layers for cheap thin film solar cells that are made from extraneous substrates such as glass and stainless steel. While the reported efficiencies of Si-based nanocrystalline thin film solar cells have been greater than the known stabilized efficiency of amorphous silicon thin film solar cells, they do not compare with reported efficiencies for silicon-based solar cells wafers This is mainly due to the recombination of minority carriers in the grain boundaries and intra-grain defects that are present in the nanocrystalline-Si absorbent layer. Therefore, the geometry of a device that allows the benefits of nanostructure and also reduces defects in grain boundaries should greatly improve efficiency, reduce the cost of the final solar cell and help increase penetration in the market. Vertically aligned silicon solar cells (SiNW) have already been theoretically shown to be much less sensitive to impurities, have low reflective losses and significantly higher optical absorption compared to Planar Si Solar cells. Several devices based on SiNW building blocks have been suggested; however, high throughput and scaling up using low cost processing approaches to produce effective devices remains a challenge. A large-volume catalytic chemical vapor deposition system and sample area has been designed and built to synthesize silicon nanowires using the vapor-liquid-solid growth process. The nanowires were made in gold plated Si type substrates. The formation of nanowires was confirmed by secondary analysis and transmission electron microscopy. An experiment design was performed to identify the SiNW process window for solar cell applications. The deposition of catalytic chemical vapor at a process pressure of 550 ° C and 150 torr produces a growth of nanowires with higher populations. P-i-n type solar cell devices were manufactured by growth of type I SiNW on a type p wafer followed by the formation of an emitter top layer using an n-type spin-on-dopant. Further optimization of the process is being carried out for the realization of solar cells of high efficiency silicon nanowires.
