Title: Kenji Yamamoto: Innovating the Future of Solar Cell Manufacturing

Introduction:

In the world of solar energy, Japanese inventor Kenji Yamamoto has left an indelible mark with his groundbreaking contributions in solar cell manufacturing. Hailing from Kobe, Japan, Yamamoto boasts an incredible portfolio of 139 patents, showcasing his profound expertise and relentless pursuit of innovation. This article delves into his latest patents, his noteworthy career highlights, and notable collaborations.

Latest Patents:

Yamamoto's recent patent, titled "Method for Manufacturing Solar Cell," demonstrates his expertise in developing an advanced manufacturing process. This innovative technique involves forming a first semiconductor layer of a specific conductivity type on a semiconductor substrate's surface. Additionally, a lift-off layer containing a silicon-based material is formed on the first semiconductor layer. Through selective removal of the lift-off layer and first semiconductor layer, a second semiconductor layer of a different conductivity type is then created. The patent highlights the importance of matching the linear expansion coefficients of the semiconductor substrate and the lift-off layer, while also emphasizing the significance of temperature control during the formation and removal process.

Another groundbreaking patent by Yamamoto is the "Photovoltaic Device," which showcases his prowess in optical systems. The invention incorporates a condensing optical system with chromatic aberration, along with a first and second photoelectric converter. The first photoelectric converter is positioned closer to the optical axis, while the second photoelectric converter, with a lower bandgap, surrounds it. This unique arrangement maximizes the absorption of longest-wavelength light, increasing the device's overall efficiency.
