The photocurrent in the reverse direction increases with increasing illumination intensity. The I-sc increases linearly with light intensity. The I-sc dependence of light intensity follows a power law I-sc similar to F-alpha. The exponent alpha was found to be 1.38. This indicates a monomolecular recombination in this device. Au/beta-carotene/n-Si organic solar cells give an open-circuit voltage of 0.316 V and a short-circuit current of 2.33 x 10(-4) A at light intensity of 6 W/m(2). The best conversion efficiency for Au/beta-carotene/ n-Si solar cells was found to be 23.3% at a light intensity of 6 W/m(2).eninfo:eu-repo/semantics/closedAccess[No Keyword]Article1102097829784WOS:0002376264000122-s2.0-337457004931670642810.1021/jp0610620Q2Q1
