What is Transmissivity Absorptivity?

Transmissivity-absorptivity is the product of a material's ability to transmit solar radiation through its surface (transmissivity) and the absorber's ability to convert this transmitted radiation into heat (absorptivity). This parameter is critical in solar collector design, as it determines how effectively solar energy is captured and utilized for thermal applications. High transmissivity and absorptivity values enhance the collector's efficiency.
