Solar energy is a clean and renewable source of energy. Solar cells usually consist of a semiconductor material that absorbs sunlight and generates electricity. However, the amount of sunlight that can be converted into electricity is limited. Standard single-junction solar cells are theoretically limited to a maximum power conversion efficiency (PCE) of 30 percent. […]
Solar is a clean, renewable energy source that can help reduce carbon dioxide emissions and reduce our impact on the natural environment. Unlike traditional fossil fuels such as coal and oil, solar energy does not directly cause pollutants (such as carbon dioxide) to be released into the atmosphere and water supply. What is a disadvantage […]

What are 4 types of radiation from the Sun? 4 types of solar radiation include: Infrared rays, Visible rays. Ultraviolet light. radio waves. What are the 4 types of radiation? There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. There is a difference between mass, energy and […]
Lithium-ion batteries are currently the preferred technology to power electric vehicles, but they’re too expensive for long-duration grid-scale energy storage systems, and lithium itself is becoming more challenging to access. While lithium does have many advantages – high energy density and capacity to be combined with renewable energy sources to support grid-level […]
This study was led by Prof. Rui Zhu, Prof. Wei Wang and Prof. Qihuang Gong from Peking University. In this work, 3-um-thick commercially available parylene-C was deposited on the top of pre-cleaned glass via chemical vapor deposition (CVD) and then the flip-over transferring (FOT) process was employed to ensure a smooth parylene surface.
