Gas absorbing body characterized in solar power generation method and apparatus based on the absorption spectrum

The present invention discloses a gas absorbing material characterized in solar power generation method and apparatus based on the absorption spectrum of species. Converting light energy absorbing device side focused sunlight into thermal energy, thermal energy is transferred to the other side of the light-conversion device, it is converted to the gas medium characteristic absorption peak of the adjacent radiation, and radiative heat transfer heat absorption chamber. Regenerator outlet gas medium into the heat-absorbing chamber, three-dimensional radiation absorption, the temperature rapidly increased. The heated working fluid temperature entering the turbine expansion work, the working fluid flows back to the heat exchanger after expansion, the temperature is lowered successively into the cooler, the compressor and the regenerator, the regenerator outlet refrigerant reentry endothermic dimensional heating chamber, a thermal power conversion cycle is completed. The present invention employs optical energy conversion device, convert the solar radiation absorption peak of the gas medium adjacent features, the working fluid is directly absorbed radiant energy perspective, significantly reducing the surface area of ​​the heat sink, the heat sink simple structure, high efficiency, low cost .
