    摘要： A photovoltaic device comprising a light absorbing structure having a general energy gap level of light absorbing material and being located between first and second electrodes configured for collection of positive and negative charge carriers therefrom respectively. The light absorbing structure is configured to provide at least one of the following: valence band energy levels being reduced by 10% -50% of the energy gap within a range of 10-lOOnm from an interface of the absorbing structure and the first electrode; and conduction band energy levels being raised by 10%-50% of the energy gap within a range of 10-lOOnm from an interface of the absorbing structure and the second electrode.
