From the use of natural fire in ancient times, to the use of wood for fire, to the use of coal and oil, the development of human civilization is essentially the development of energy utilization capabilities. So far, contemporary human civilization and economic development are largely based on the development and utilization of fossil energy. In the 21st century, due to concerns about the non-renewable fossil energy reserves on the earth and the increasingly serious environmental pollution caused by the exploitation and use of fossil energy, people have turned their attention to green and sustainable energy fields, such as Solar, wind, hydro…
“Only by solving the scientific problems of efficient utilization of solar energy is the road to sustainable development of mankind.” Professor Chen Yongsheng from the School of Chemistry of Nankai University asserted, “The sun is the mother of all things and the ‘source’ of energy. The sun that reaches the earth every moment If two ten-thousandths of light energy can be utilized, it can meet all the energy needs of the current human society.” Because of this, among the various technologies that humans use solar energy, solar cells, that is, using the “photovoltaic effect” will Devices that directly convert light energy into electrical energy have been widely used and are also one of the most promising technologies.
For a long time, people have made more solar cells based on inorganic materials such as crystalline silicon. Using the most abundant carbon material on the earth as the basic raw material, obtaining high-efficiency and low-cost green energy through technical means is of great significance for solving the major energy problems facing human beings.
