Local collection efficiency in the nano-crystalline solar cells

Efficiency improvement of crystalline silicon solar cells

To increase the efficiency and reduce the production cost of crystalline silicon (c-Si) solar cells, efforts in the photovoltaic industry are currently put on the process optimization of the cell. Sodium hydroxide/Potassium hydroxide (NaOH/KOH) and isopropyl alcohol (IPA) are widely used in the standard alkaline texturization of mono crystalline silicon (mc-Si) wafers for enhancing the optical ...

High Efficiency Mono-crystalline Solar Cells with Simple Manufacturable Technology

This paper describes the analysis and optimization of phosphorus-doped n emitters for Si solar cells with screen-printed contacts to improve the uniformity of contact formation. Analysis of the simulated emitters showed that Joe increases with the increase in phosphorus surface concentration. Cells fabricated on emitter having a higher surface concentration and shallower junction depth, were on...

High-efficiency heterojunction solar cells on crystalline germanium substrates

Crystalline Silicon Solar Cells

Front page headlines in the New York Times and the Wall Street Journal in 1954 heralded to the world the demonstration of the first reasonably efficient solar cells, an event made possible by the rapid development of crystalline silicon technology for miniaturised electronics. Since that time, the majority of solar cells fabricated to date have been based on silicon in monocrystalline or large-...

Nano-Structured Solar Cells

2.0 The resources at Arkansas are more than adequate. The team is very capable and can realize the stated goals. The results have shown that there is a chemical interaction between carbon nanotubes and P3HT. Solar panels based on carbon nanotube/P3HT organic materials were disappointingly low. Goals have been set to increase the efficiency. Some very preliminary results based on Si were given b...
