Solar panel are incapable of generating heat.
 This technology was later put into mass production as dual layer, dual panel or LMCL (Light Modulating Cell Layer) LCDs
LCDs are themselves slowly being replaced by OLED displays, which can easily be made into different shapes, have a lower response time, wider color gamut, virtually infinite color contrast and viewing angles, lower weight for a given size, a slimmer profile and potentially lower power consumption
