R. Shimokawa et al., SUB-5 MU-M THIN-FILM C-SI SOLAR-CELL AND OPTICAL CONFINEMENT BY DIFFUSE REFLECTIVE-SUBSTRATE, Solar energy materials and solar cells, 34(1-4), 1994, pp. 277-283
Thin film (4.2 mu m) c-Si cell with the superior short-circuit current
of 25.5 mA/cm(2) which is comparable to that of cast Si solar cells w
as realized by the improvement of anti-reflection coating and diffuse
reflective-substrate It was confirmed that this superior short-circuit
current characteristics was due to the optical confinement based on i
nternal randomization.
