New Generation Silicon Solar Cells

5.3 Reflection

New Generation Silicon Solar Cells

3. Back side reflection

Two different layers at the backside:

Patterns of microscopic spheres of glass within

a precisely designed photonic crystall

Capture and recycle the photons

Large-scale manufacturing techniques are

being developed

advantage:

Reflects more light than the aluminium layer

Light reenters the silicon at low angle light

bounces around inside

Efficiency can be increased up to 37%

a)

represents the aluminium layer

b)

represents the new version
