Solar Cells
We are the one of just a few companies building monocrystalline Solar Cells on both P-type and N-type Si. This approach results in the enhanced cell output parameters as well as the wide range of applications, all achieved at low affordable price. Cell structures outlined below:
n+- p - p+ - for P-type starting material
p+ - n - n+ - for N-type starting material
 |
1 - textured surface with ARC
2 - n+ (p+) - Si
3 - p (n) - Si
4 - p+ (n+) - Si
5 - metall
6 - sun radiation
|
- front surface textured
- <100> wafer orientation
- back side can be either plain or textured
- printed contact grids on both sides
Both P-type and N- type cells are transparent to the IR spectrum resulting in slower heat rate and lower cell temperature, which increases cell efficiency.

Our company has started producing two-side sensitive Si Solar Cells, both P- and N-type, as a part of the world earliest efforts.
Solar Wind manufactures various pseudo-quadratic cells with the typical dimensions of 103.5x103.5 mm (diametr 125 mm and 135 mm), 125x125 mm (diametr 150 mm), 175È150 mm (diametr 200 mm), partial cells are available too.

Temperature Parameters:
| Short Circuit Current, [1/°C] | (0.71 ± 0.13)*10-3 |
| Open Circuit Voltage, [mV/°C] | -(1.96 ± 0.15) |
| Output Power, [1/°C] | -(0.55 ± 0.06)*10-2 |
