High Efficiency Polymer-Titanium Oxide Hybrid Solar 토토 사이트 바카라s

Increasing demands for highly efficient sources of renewable energy is motivating scientists to explore novel approaches. Polymer solar 토토 사이트 바카라s represent a promising route, but the efficiency in converting sunlight into useable electric power is still relatively low compared with inorganic technology based on silicon semiconductors. Recently we have demonstrated polymer tandem solar 토토 사이트 바카라s with a power conversion efficiency of 6.5%, with each layer processed from solution. A transparent TiOx layer is used to separate and connect the front 토토 사이트 바카라 and the back 토토 사이트 바카라. The TiOx layer serves as an electron transport and collecting layer for the first 토토 사이트 바카라 and as a stable foundation that enables the fabrication of the second 토토 사이트 바카라 to complete the tandem 토토 사이트 바카라 architecture. We use an inverted structure with the low band-gap polymer/fullerene composite as the charge separating layer in the front 토토 사이트 바카라 and the high band-gap polymer composite as the charge separating layer in the back 토토 사이트 바카라. We also believe that polymer tandem 토토 사이트 바카라s utilizing both new materials with tuned absorption spectra as well as high mobility and series stacking of the sub 토토 사이트 바카라s will yield results approaching 15% efficiency in the near future.
