Title Clean Energy Technology Development Strategy
In December 2015, one of the important aspects of the Paris Agreement is that more than 20 countries, including the Republic of Korea, the United States, France, China, and Japan, participated in the Mission Innovation. Each participating country will seek to double its governmental clean energy research and development investment over five years, to address climate change and reduce greenhouse gas emissions. The Republic of Korea decided that it would endeavor to double its clean energy R&D investment over five years from USD $490 million in fiscal year 2016 to USD $980 million in fiscal year 2021. The Korean government established a long-term technology development roadmap,“Clean Energy Technology Roadmap” to support investment doubling plan. Clean Energy Technology Roadmap serves as a milestone for clean energy technology development in order to achieve a low-carbon society, and realizes energy policy directions of the Korean government which attempt to take advantage of climate change as a new business opportunity. The thirteen core technologies on the roadmap are photovoltaic, wind, hydrogen‧fuel cell, bioenergy, transportation energy efficiency, industry energy efficiency, building energy efficiency, e-prosumer, ESS(energy storage system), clean thermal power, smartgrid, nuclear power, and CCUS(carbon capture, utilization, and storage). Investment for clean energy technology development will be shared by the government and public enterprises to enhance investment efficiency. In particular, government will invest with a focus on CCUS, renewables, demand management, and energy efficiency improvement, and public enterprises will expand their investments towards clean thermal power, transmission and distribution, and nuclear power.

Title Nanogenerators for self-powered flexible electronics and piezotronics for active human-machine interfacing
Developing wireless nanodevices and nanosystems is of critical importance for sensing, medical science, environmental/infrastructure monitoring, defense technology and even personal electronics. It is highly desirable for wireless devices to be self-powered without using battery. Nanogenerators (NGs) have been developed based on piezoelectric, trioboelectric and pyroelectric effects, aiming at building self-sufficient power sources for mico/nano-systems. The output of the nanogenerators now is high enough to drive a wireless sensor system and charge a battery for a cell phone, and they are becoming a vital technology for sustainable, independent and maintenance free operation of micro/nano-systems and mobile/portable electronics. An energy conversion efficiency of 55% and an output power density of 500 W/m2 have been demonstrated. This technology is now not only capable of driving portable electronics, but also has the potential for harvesting wind and ocean wave energy for large-scale power application. This talk will focus on the updated progress in NGs. For Wurtzite and zinc blend structures that have non-central symmetry, such as ZnO, GaN and InN, a piezoelectric potential (piezopotential) is created in the crystal by applying a strain. Such piezopotential can serve as a “gate” voltage that can effectively tune/control the charge transport across an interface/junction; electronics fabricated based on such a mechanism is coined as piezotronics, with applications in force/pressure triggered/controlled electronic devices, sensors, logic units and memory. By using the piezotronic effect, we show that the optoelectronc devices fabricated using wurtzite materials can have superior performance as solar cell, photon detector and light emitting diode. Piezotronics is likely to serve as a “mechanosensation” for directly interfacing biomechanical action with silicon based technology and active flexible electronics. This lecture will focus on the updated progress in the field and its expansion to 2D materials.
