Electrochromic devices

Research activities


The Renewable Energy Laboratory has considerable experience in the design, fabrication and testing of solar energy materials and devices for photovoltaic and solar thermal applications. We specialize in the development of thin film semiconductors (WO3, TiO2, ZnO, CdS, CdTe, MoO3) for dye sensitized and thin film solar cells. We have the capability of producing thin films in high vacuum conditions using different techniques, such as electron gun deposition and thermal evaporation. A large variety of films (metals, dielectrics, oxides, sulfides) can be deposited on virtually any type of substrate (glass, silicon, quartz, polymer), with thickness ranging from the sub-nm to several μm. Sol-gel, doctor blade and electrochemical deposition techniques are also used. We have also acquired expertise in the testing of solar energy devices in outdoor conditions.  Our laboratory has played an integral role in the design and construction of the first Greek Solar Car, “Hermes” and is the principal scientific collaborator of a Greek micromorphic Si photovoltaic facility.


Original large surface electrochromic devices for smart window applications have been constructed and thoroughly tested. Photo-electrochromic devices, a combination of the photovoltaic and electrochromic technologies are currently under development. We have considerable experience in the measurement of thermo-physical properties of building components.


Micro and nano scale thin films on various substrates for fuel cell (solid electrolyte YSZ) and H2 production applications have been studied and optimized. Electrochemical techniques such as electrodeposition have been used to produce binary and ternary alloys and inter-metallic compounds.
