Sand? Lie. It's quarts not sand because sand is contaminated with other elements. It's mining that provides the quarts that is crushed and heated with coal to crystalize

This is rubbish, Quartz and coal (around 10 tonnes) are used to make solar panels, NOT sand or silicon as you put it. The raw material for the solar panels is coal, which has an average life of 11 years. This means that 11 tons of coal must be burned to make a solar panel - that’s about 3000 pounds! The production process uses high temperatures and pressures.

What is difference between P type and n type modules

@Ericrueland007 Жыл бұрын

It is the different cell technology used. Standard (traditional) solar cells are p-type. Using Boron for initial doping of the silicon - making the silicon wafer p-type (or with a majority of holes not electrons for conductivity). The phosphor is used to make the p/n-junction or diode in a standard cell. For n-type it is the opposite: the silicon wafer material is doped with phosphor and the layer is made of Boron doping. At the end: n-type is a bit more complicate to manufacture, but gives higher efficiencies. Therefore it seems to be the near future...

The solar panel manufacturing is connected with the lowest invest needed. For a capacity of 100MW per year the invest for a solar module fab (you have to purchase the glass, laminate and solar cells) might be in the range of 15 Mio US $. on greenfield. But invest in solarmodule plants is just around 0,5 US$ per Watt installed. Giving a electricity cost of app. 0,05 US$ in sunny regions.

Rubbish, SOLAR CELLS are not made with any sand, that is too impure to use, they use a pure quartz and a high grade coal, they melt the coal and quartz and out comes the raw material to make the solar cell. It takes a huge amount of energy to make them, so these are not green by any means.

you are right, that quartz sand is needed. But this is not a major game changer as quartz sand is widely available.
