Our research group focused on a photoelectrochemical (PEC) water splitting system to produce the hydrogen energy by semiconducting materials and solar energy. To enhance the solar-to-hydrogen (STH) conversion efficiency, various strategies (doping, nano-structuring, junction, surface modification, and DFT calculation) of semiconducting electrode have been studied in our laboratory. Our main goal is to develop a high-performance PEC system that can lead to a green hydrogen society. Solar desalination, which utilizes solar energy, is a promising technology for converting seawater into fresh water. Its advantages include reducing environmental impact, addressing water shortages, and relying on abundant resources such as water, and solar energy. As evaporation is a surface phenomenon, solar desalination is based on the interfacial evaporation principle using a photoabsorber, which is the same as natural evaporation. Zinc-Ion batteries are a type of rechargeable battery that uses zinc ions as the charge carriers. They have emerged as a promising alternative to traditional batteries due to their numerous advantages such as safety, higher theoretical volumetric capacity of Zn (820 mAh/g) , non-toxicity, and easy processibility, abundant raw material resources, low cost compared to lithium-ion batteries. Improving semiconductor integrated circuit's performance by reducing critical dimensions and implementing high-resolution patterns is entirely dependent on the resolution limit of lithography. circuit line width of semiconductors are getting shorter and higher resolution patterns are required. Extreme Ultra Violet (EUV) lithography is the promising technique of next-generation semiconductors that can overcome this limitation. However, existing organic chemically amplified resis
