M. Sharon et al., A PHOTOELECTROCHEMICAL SOLAR-CELL FROM CAMPHORIC P-CARBON SEMICONDUCTOR, Solar energy materials and solar cells, 45(1), 1997, pp. 35-41
A photoelectrochemical solar cell from camphoric p-carbon semiconducti
ng pellet has been developed for the first time from the soot of a nat
ural source, camphor. This semiconducting camphoric carbon is unusuall
y stable both in acidic and alkaline media. Preliminary findings show
that the semiconductor has band gaps (E(g) 2.28 eV direct and 1.28 eV
indirect) suitable for solar energy conversion. PEC properties are als
o being discussed.
