On the 28th, the world's first expressway photovoltaic pavement test section with completely independent intellectual property rights was officially opened to traffic in Jinan. This "photovoltaic high-speed" with a length of more than 1,000 meters can convert light energy into electrical energy. Not only can it melt snow at any time, but it can also transmit electricity to the power grid in real time, just like a giant "charging treasure". At the same time, an electromagnetic induction coil is reserved under the road, and electric vehicles can be charged while running in the future. It is understood that this is the first time in the world that the photovoltaic photovoltaic pavement technology has been applied to the most stringent highways.

Load-bearing photovoltaic pavement technology is a technology in which photovoltaic power generation components that meet the traffic conditions of vehicles are directly laid on the road pavement, thereby realizing solar power generation and other related functions. In layman's terms, the top layer of this highway is a new type of translucent material similar to frosted glass, which has a higher coefficient of friction than traditional asphalt pavements, while ensuring that the tire does not slip, it also has a high light transmittance, which allows sunlight to penetrate It enables the solar cells below to convert light energy into electrical energy and transmit it to the grid in real time.

Xu Chunfu, chairman of Qilu Transportation Development Group, told reporters that since the start of the project in December 2016, Qilu Transportation has joined forces with Tongji University and Guangshi Energy to carry out in-depth cooperation in production, teaching and research, focusing on the industrialization of photovoltaic road technology deepening and engineering applications Research, systematic research on basic system design, industrial component production, and derivative product development, successfully integrating road traffic functions and power generation functions on new photovoltaic pavement, using three layers of "transparent concrete + photovoltaic power generation components + insulation protection" The structure, design life, mechanical parameters and road performance are all higher than the existing asphalt concrete pavement.
