The effects of metal (Ni or Pb) and Langmuir-Blodgett (LB) films on the photoelectrochem. behavior of n-Si were studied. Ni and Pb can improve the energy conversion efficiency and the stability of n-Si. The modification of n-Si/Ni by LB films prepared with eight different organic compounds was determine and discussed; the efficiency of the photoelectrode was doubled by the best compound (long-chain coumarin LB film). The photoelectrochem. properties of Si/LB/Al electrode having the MIS structure were also studied.
