Tunable photovoltaic electrochromic device and module

Integration of polyelectrolyte based electrochromic material in printable photovoltaic electrochromic module

“…Details about fabrication of semi-transparent Si-TFSC were reported earlier in our published paper [22,26]. The structure of the Si-TFSC included a glass substrate, a ZnO:Al transparent conducting oxide layer which served as the anode, a double junction of amorphous and microcrystalline Silicon (a-Si:H/μc-Si:H) thin films which served as the photoelectric conversion layers, and a ZnO:Al layer and a back reflector metal layer together to constitute the cathode.…”

“…This ionic current migrates transversely along the electrodes of the Si-TFSCs, in order to maintain charge neutrality in the device. The cations and anions in the PANI/PSS NSTF are attracted to the anodes and cathodes of the Si-TFSCs, respectively, inducing color change in the ECTFs [21,22].…”

“…Until recently, there are several types of solar powered electrochromic devices available: tandem structure silicon (Si) based PV-EC device [15][16][17][18], dye-sensitized solar cell (DSSC) based photoelectrochromic (PEC) device [19,20], and planar structure Si based PV-EC device [21,22].…”

“…In our previous studies, both solution type and solid type PV-EC devices have been constructed based on the integration of planar structured silicon thin film solar cells (Si-TFSCs) with electrochromic solution [21], and with successively deposited EC layers [22]. The cathode of the Si-TFSCs is arranged in stripes, and the area outside the cathode blocks contains anode which is composed only of transparent conductive oxide (TCO).…”

Electrochemical and electrochromic behaviors of polyaniline-graphene oxide composites on the glass substrate/Ag nano-film electrodes prepared by vertical target pulsed laser deposition

“…The electrochromic devices (ECDs) with a wide viewing angle, low switch potential have caused the widespread concern and it can be used in the areas of camouflage materials, intelligent materials, new display devices, and so on [3][4][5][6]. The typical ECD composition is a five-layer of GS/TC/EC/IC/IS/TC/GS, where GS is a glass substrate, TC is a transparent conductor, EC is an electrochromic coating, IC is an ion conductor and IS is an ion storage coating.…”
