Key innovations
The innovation of this product lies in its independently developed graphene composite coating material, which achieves multi-functional integration of infrared conversion, ultra-hydrophilic self-cleaning and anti-reflection, significantly increasing photovoltaic power generation capacity and reaching the international leading level.
Potential economic benefits
It can increase photovoltaic power generation capacity by more than 5%, extend equipment life, reduce operation and maintenance expenses, and significantly increase the total revenue of the power station. Good economic benefits have been achieved.
Potential climate benefits
The graphene coating significantly increases photovoltaic power generation by more than 4%, directly increases clean energy supply, replaces fossil fuels, and significantly reduces carbon emissions from power generation. At the same time, extending the life of photovoltaic panels reduces the implicit carbon footprint of new panel manufacturing and old panel processing. Ultra-hydrophilic self-cleaning also reduces maintenance energy consumption and related emissions.

Solution details

1. application field

Photovoltaic cell modules face three problems in operation and maintenance.(1) The use environment of photovoltaic panels is poor, such as dust, sand, bird droppings and other pollution, which greatly reduces power generation. (2) The temperature difference of photovoltaic panels changes greatly, resulting in increased heat radiation loss of the unit and reduced service life. (3) The surface reflectivity of photovoltaic glass is as high as 8%, resulting in a decrease in solar output energy.

2. technical characteristics

It adopts a self-developed graphene composite coating material, which has excellent characteristics such as infrared light conversion, ultra-hydrophilic self-cleaning, and visible light transmittance enhancement. The comprehensive additional power supply exceeds that of similar foreign products, and is at the international leading level.

3. performance Index

(1) The power generation capacity of photovoltaic cells increases by>4%;(2) Super hydrophilicity: pure water contact angle <5 degrees;(3) Anti-transmittance: light transmittance increases by>2%;(4) Aging resistance: ≥500h;(5) Coating hardness: ≥ 2H

4. current state

Materials have been mass-produced on a large scale and have been applied in real estate industries such as Inner Mongolia, Yunnan, and Zhejiang, with an implementation area of more than 60,000 square meters. The additional issuance of photovoltaic power stations is>5%. Achieve good economic benefits.
