We have fabricated high-efficiency a-Si/µc-Si tandem solar cells and modules with a very high µc-Si deposition rate using Localized Plasma Confinement CVD to give very high-rate deposition (>2.0 nm/s) of device-grade µc-Si layers. For further prog

A fabrication technology for high-quality, device-grade microcrystalline silicon (μc-Si) thin film with a higher deposition rate has been required to reduce the production cost of amorphous silicon (a-Si)/μc-Si tandem modules. Localized Plasma Conf

An ‘Aurora PLD method,’ in which a magnetic field is applied to a plasma plume, was employed to grow ZnO films and to study the mechanism of crystal growth. In the Aurora PLD method, the ZnO target displayed a brighter plume in the vicinity of th

Undoped microcrystalline silicon with various crystallinities was deposited by rf-glow discharge. We investigate the correlation between crystallinity and optoelectronic properties. The use of a constant photocurrent method for characterization of un

The experimental spectral response and reflectance of high-efficiency a-Si solar cells are systematically investigated by using an optical simulation based on realistic optical properties of the transparent conducting oxide (TCO), a-Si, and metal ele

A solar cell is a large-area diode with a p-n or a p-i-n junction. Since the invention of the first solar cell with a p-n junction by G.L. Pearson et al. in 1954, various types of solar cells have been investigated. Especially in the decade since 200

We developed a high-conversion-efficiency, a-Si/µc-Si tandem solar module using µc-Si thin film on a Gen. 5 class glass substrate. The stabilized module efficiency was 10.7% (initial module efficiency: 12.0%). We prepared high-performance a-Si/µc-

The quantum size effect allows the use of silicon nanowires and nanowalls for the top cell of all-Si tandem solar cells by tuning the band gap. However, these Si nanostructures are far thinner than the wavelength of visible light in the direction of
