Technical Name Fabrication of dye-sensitized solar cells by printing processits applications on Internet-of-Thing (IoT)
Project Operator National Cheng Kung University Hierarchical Green-Energy Materials (Hi-GEM) Research Center
Project Host 李玉郎
On base of the advantages of dye-sensitized solar cells (DSSCs), including easy fabrication process, low cost,the high energy conversion efficiency under room light conditions, DSSCs were utilized as self-power suppliers for devices involved in internet-of-things (IoT) systems.
Scientific Breakthrough
1.	Gel-electrolyte of DSSCs are prepared for operation by printing process. This technique is beneficial for the pore fillingthe roll-to-roll production process of DSSCs.
2.	Highly activelight transmittance counter electrodes are prepared which are used to fabricate bi-facial DSSCs. The cells can work on both frontthe back sides, producing more energy.
Industrial Applicability
1. Development of gel-type electrolytes for dye-sensitized solar cells (DSSCs). The electrolytes with printing properties can be applied to the roll-to-roll process for mass production of module devices.
2. Development of highly catalytictransparent counter electrodes. 
3. Light harvesting in both outdoorindoor environments.
