Q:The difference between a fuel cell and a solar cell
At present fuel cell system fuel - power conversion efficiency of 45% to 60%, while the thermal power and nuclear power efficiency of about 30% to 40%. (2) Hazardous gases SOx, NOx and noise emissions are low CO2 emissions are greatly reduced due to high energy conversion efficiency, no mechanical vibration.
Q:Can the 156x156mm high efficiency single crystal cells assembly function better compared to the traditional one?
The reason why it is functioning better is because of its h igh power large area silicon solar cell.
Q:Is the Photovoltaic Cells cheap to buy?
It used to be very expensive around 35 years ago because of all the labor cost and R&D expense, but now it is not as expensive as before.
Q:Can the solar powered cells really work better than the normal cells?
Yes, it does work much better than the normal cells, but the solar powered cells also has its disadvanges.
Q:Are bulk solar cells better than the normal solar cells?
Bulk solar cells are not absolutely better than normal solar cells, it is decided by what kind of material.
Q:How do solar cells work to become the solar energy?
Solar Energy Materials & Solar Cells is intended as a vehicle for the dissemination of research results on materials science and technology related to photovoltaic, photothermal and photoelectrochemical solar energy conversion.
Q:I studied very hard at school, but I just can not figure out how solar cells work, anybody can help me with that?
It's not a easy job.
Q:How long does it take to make a solar cell?
It only took me 1 day because I had all the required materials ready before I start to make it.
Q:What are the applications of solar cells?
User solar power: - small power supply 10 ~ 100W range, for remote areas such as the plateau, islands, pastoral areas, border posts and other military life electricity, such as lighting, television, tape recorders and so on. - 3 ~ 5KW home roof grid-connected power generation system. - PV water pump: to solve the non-electric areas of deep wells drinking, irrigation.
Q:What's the relationship between solar energy materials and solar cells?
There are solar cells made of many different kinds of materials, for example: Silicon thin film, compound semiconductor thin film and organic thin film shape, hundreds of compound semiconductor thin film shape and non crystalline shape (a-Si: H, a-Si:H:F, a-SixGel-x:H) III V family (GaAs, InP), II VI (CDS) and zinc phosphide (Zn3P2).
