Are thin crystalline silicon solar cells effective?

Lightweight and flexible thin crystalline silicon solar cells have huge market potential but remain relatively unexplored. Here, authors present a thin silicon structure with reinforced ring to prepare free-standing 4.7-μm 4-inch silicon wafers, achieving efficiency of 20.33% for 28-μm solar cells.

Do silicon-based ultra-thin solar cells inherited their characteristics well?

Consequently, the silicon-based ultra-thin solar cell inherited their characteristics very well when both the optimal silicon surface grating and bottom metal grating are applied at the same time, thereby increasing the absorption rate of the solar cell in the entire waveband.

How efficient is a thin active layer silicon solar cell?

What is the efficiency of ultrathin silicon solar cells?

Adv. Mater. 27, 2182–2188 (2015). This paper reports the first ultrathin silicon solar cell (t = 10 μm) with a short-circuit current exceeding significantly single-pass absorption and leading to an efficiency η = 15.7%. Gaucher, A. et al. Ultrathin epitaxial silicon solar cells with inverted nanopyramid arrays for efficient light trapping.

Are thin Si solar cells efficient?

However, thin Si solar cells with nanostructures are not efficient because of severe Auger recombination and increased surface area, normally yielding <50% EQE with short-wavelength light. Here we demonstrate >80% EQEs at wavelengths from 400 to 800 nm in a sub-10-μm-thick Si solar cell, resulting in 13.7% power conversion efficiency.

Can thin silicon solar cells be blunted?

Recently, a technique of blunting pyramidal structure in the marginal regions was proposed by Liu et al. for thin silicon solar cells with a thickness of around 60 μm 2. However, for thinner silicon wafers, there could be a lot of breakage before blunting pyramids.
