– [Hope] Technology to produce solar cell from wood pulp is developed, “Manufacturing cost is 1/100,000″ (Fukushima Diary, Feb 19, 2013):
Associate professor Nogi from Osaka university developed the technology to produce solar cell from wood pulp with his developing team.
The manufacturing cost is 1/100,000 of the one with glass substrates, 1/500 ~ 5,000 of the one with plastic.
It’s wired by pressure instead of heating, which takes less energy to lessen the environmental burden.
The conversion efficiency is 3%, which is less than the ordinary solar power generation panel attached on the roofs, (10~20%) but the same level as the one with glass substrates.
It’s less than 1mm thick, and it’s foldable.
