6 FAQs about [Han Togo Solar Cell]

How efficient is a heterojunction back contact solar cell?

In 2017, Kaneka Corporation in Japan realized heterojunction back contact (HBC) solar cell with an efficiency of up to 26.7% (JSC of 42.5 mA·cm −2) 25, 26, and recently, LONGi Corporation in China has announced a new record efficiency of 27.30% 16.

Does TTO affect the photoelectric tradeoff in SHJ solar cells?

Notably, the Anti-Burstein-Moss effect of TTO is observed, which is ascribed to variations of stress in films. Based on this finding, TTO was first applied to SHJ solar cells, and the photoelectric tradeoff in front and rear contacts is gained by matching nanocrystalline silicon layers and adjusting TTO thickness.

How efficient are silicon heterojunction solar cells?

Lin, H. et al. Silicon heterojunction solar cells with up to 26.81% efficiency achieved by electrically optimized nanocrystalline-silicon hole contact layers. Nat. Energy 8, 789–799 (2023). Lin, H. et al. Unveiling the mechanism of attaining high fill factor in silicon solar cells. Prog. Photovolt. Res. Appl. 1–13 (2024).

Can tto be used as a transparent electrode in SHJ solar cells?

Here, TTO was selected as indium-free TCO, and the TTO films prepared at low-temperature (≤ 200 °C) was first applied as transparent electrodes in SHJ solar cells. The replacement of a-Si:H by nc-Si:H has significantly improved the efficiency of indium-free SHJ solar cells based on TTO.

Can tandem solar cells boost efficiency?

Can tto be applied to SHJ solar cells?

TTO was applied to SHJ solar cells to obtain efficient indium-free SHJ solar cells. TTO-based indium-free SHJ solar cell achieved an efficiency of 25.15 % with a certified efficiency of 25.10 % (274.3 cm 2). Reducing indium consumption has received increasing attention in contact schemes of high efficiency silicon heterojunction (SHJ) solar cells.
