Glass ir absorption for solar panels.

The solar cells are highly transparent in near infrared region with an optical transmittance of nearly 80 in the range of 670 nm to 1 2 μm and maintain a transmittance of above 60 through 1 2. Infrared reflective or ir glass works by filtering out only infrared waves from sunlight but allowing all visible light which allows us to see making the glass transparent. Solar radiant energy entering a room through the glass is absorbed by interior objects and surfaces which then retransmit the energy as thermal radiation see thermal insulation glazing mainly in the far infra red band above 5 µm. Greenhouse windows treated with special quantum dots will actually convert part of the sunlight s blue spectrum during absorption.

While ir windshields do not reflect all infrared rays up to 50 of the ir energy can be reflected back into the atmosphere and cool your car or truck to up to 10 degrees. The 9 8 percent power conversion efficiency of the small sized organic solar cell. Even ordinary float glass is practically opaque to radiation with a wavelength higher than 5 µm. They are an important component in a number of electronic devices including liquid crystal displays oleds touchscreens and photovoltaics.
