Paper Abstract

Liquid crystal window has been considered as an optical shutter to control the solar energy. Investigation of various types of liquid crystal cells show that the phase change guest host (PCGH) type would be better to fabricate large size LC-cell. PCGH-cell with black dye has anormalous transmission dip near the threshold voltage for incoherent light in the range of 400 to 500nm. The anomalous dip is shown to come from scattering of incident light by the voltage induced inhomogeneities created during the phase transformation. 6μm thick 12.5cm x 12.5 cm LC-window has been fabricated using PCGH-LC mixture. The transmittance of the window could be controlled to an accuracy of less than 1% using IBM-PC computer.
