6 FAQs about [Silicon-based solar power generation has low efficiency]

How efficient are silicon solar cells?

Using only 3–20 μm -thick silicon, resulting in low bulk-recombination loss, our silicon solar cells are projected to achieve up to 31% conversion efficiency, using realistic values of surface recombination, Auger recombination and overall carrier lifetime.

How efficient are solar cells?

Photovoltaic (PV) conversion of solar energy starts to give an appreciable contribution to power generation in many countries, with more than 90% of the global PV market relying on solar cells based on crystalline silicon (c-Si). The current efficiency record of c-Si solar cells is 26.7%, against an intrinsic limit of ~29%.

What is the limiting efficiency of a silicon solar cell?

The best real-world silicon solar cell to date, developed by Kaneka Corporation, is able to achieve 26.7% conversion efficiency 7, 8. A loss analysis of this 165 μm -thick, heterojunction IBC cell shows that in absence of any extrinsic loss mechanism the limiting efficiency of such a cell would be 29.1% 7.

How efficient are silicon heterojunction solar cells?

Here, we present the progresses in silicon heterojunction (SHJ) solar cell technology to attain a record efficiency of 26.6% for p-type silicon solar cells. Notably, these cells were manufactured on M6 wafers using a research and development (R&D) production process that aligns with mass production capabilities.

What is the power conversion efficiency of a solar cell?

The power conversion efficiency of a solar cell is a parameter that quantifies the proportion of incident power converted into electricity. The Shockley-Queisser (SQ) model sets an upper limit on the conversion efficiency for a single-gap cell.

Why do thick silicon solar cells lose power?

Moreover, thick silicon solar cells suffer from unavoidable losses in power conversion efficiency due to non-radiative recombination of photo-generated charge carriers during their relatively long path to electrical contacts at the extremities of the cell.
