"top layer is a paramagnetic insulator made of gadolinium gallium garnet. This layer is transparent to sunlight and emits thermal radiation to the universe, getting cooler. Sunlight passes through the following ferrimagnetic layer made of yttrium iron garnet. This layer is also transparent... bottom two light-absorbing layers, made of paramagnetic platinum and blackbody paint. The bottom section stays warm due to sunlight absorption... converted to electric voltage in the paramagnetic platinum layer"
