Abstract :
The fullerene thin films (bucky balls) on irradiation are found to undergo cracking (disintegration) resulting in the formation of the conducting amorphous carbon. Reduction in the resistivity and optical gap were observed during the irradiation process. The films on boron and phosphorous ion implantation resulted in the p and n type semiconducting amorphous carbon. Solar cells fabricated from the excimer laser irradiated films of C/sub 60/ sandwiched with n-type Si resulted in the efficiency of 0.7%.
