The n-type emitter of most crystalline p-type silicon solar cells is formed by phosphorus diffusion.A common P diffusion method is to expose Si wafers in a furnace at about 800–900 °C to an atmosphere of POCl 3 and O 2 (with N 2 as a carrier gas), forming a phosphosilicate glass (PSG) on the wafer surfaces. This process step is usually called …

Discussion of the advantages of the DSSC compared to silicon-based PV cells. Guidance: In a photovoltaic cell the light is absorbed and the charges separated in the silicon semiconductor. The processes of absorption and charge separation are separated in a dye-sensitized solar cell.
In comparison, the working principle of this solar cell is quite different from perovskite solar cells and inorganic p–n junction solar cells. When OPVs are illuminated, a localised and strongly bound exciton (i.e. a bound electron–hole pair) is generated, with the electron in the LUMO (lowest unoccupied molecular orbital) and the hole in ...
