Abstract

The technological innovation of the direct conversion of solar energy to electric plays an important role in electric power generation. Earlier discussions of band bending in a semiconductor contacting a metal and liquid electrolyte solutions containing redox couples with different electrochemical potentials should not overshadow the fact that under absorption of photons takes place in a solar cell, which can generate free charge for an electrical circuit. Here we propose new band bending of ZnO and Cu2O semiconductors induced by a liquid self-assembled microdrop of a physiological salt solution.
