Can thin-film silicon absorbers save energy compared to full-silicon-wafer technology?
Alternatively, thin-film multicrystalline (mc) silicon on glass can help to save both energy and material consumption compared to full-silicon-wafer technologies. Competitive PV conversion efficiencies can be expected on thin-film silicon absorbers (10 – 15 µm) using a photonic-crystal light-trapping structure.

How thick are the free-standing silicon wafers?
Here, we present a thin silicon with reinforced ring (TSRR) structure, which is successfully used to prepare free-standing 4.7-μm 4-inch silicon wafers. This is mainly caused by the brittleness of silicon wafers and the lack of a solution that can well address the high breakage rate during thin solar cells fabrication.
Why are thin silicon wafers prone to breaking?
The main challenge in fabricating thin solar cells is the high breakage rate of silicon wafers due to their brittleness. To address this, we present a thin silicon with reinforced ring (TSRR) structure, which enables the production of free-standing 4.7-μm 4-inch silicon wafers.
How does 3D wafer technology produce thin wafers?
