Abstract :
Amorphous carbon (a-C) as a semiconductor in heterojunction solar cells, such as C/Si, C/GaAs, etc., were already reported by various groups. Here, we present the rectifying current-voltage characteristics of n-C/p-C junction. The cell, n-C/p-C on p-Si substrate, reveals a short circuit current density of 23.04 mA/cm2, open circuit voltage of 0.346 V, and a power conversion efficiency of 2.28%, under AM0 and 1 sun illumination conditions. The spectral response of the cell was explained through the absorption characteristics of the two individual carbon layers
