Nature has been inspiring mankind for centuries. From antiques to paintings, from fashion to interior design, nature is truly all around. The latest inspiration is in technology, which will have us bid farewell to rectangular solar panels. The next generation of photovoltaics is a leaf-shaped design that perfectly mimics nature’s pattern of absorbing solar energy.
Nature has inspired the next generation of solar technology
The world is experiencing tremendous pressure to mitigate climate change. Renewable energy sources are the go-to solution, with solar energy being the most popular in certain regions of the world. Photovoltaic cells convert the sun’s heat energy into power. However, according to EcoFlow, traditional rectangular photovoltaics have challenges of their own, such as low efficiency.
Thankfully, a research team from Imperial College London engineered a leaf-shaped photovoltaic cell that mimics nature’s real-life plants. This latest design will trump all others. Their research article, ‘High-efficiency bio-inspired hybrid multi-generation photovoltaic leaf,’ was published in Nature Communications.
“This innovative design holds tremendous potential for significantly enhancing the performance of solar panels, while also ensuring cost-effectiveness and practicality.” – Dr Gan Huang, Honorary Research Fellow in the Department of Chemical Engineering, and author of the new study.
This leaf-shaped photovoltaic cell trumps all others
Nature’s inspiration has done it again, this time through transpiration. Transpiration is the process through which water shifts from a plant’s roots to the end of its leaves. The research team engineered the leaf-shaped photovoltaic cell to mimic this process. Water shifts, distributes, and evaporates through the leaf-shaped photovoltaic cell. The cell also has natural fibers that mimic the veins of leaves, and hydrogels that act as sponge cells to efficiently and affordably remove excess heat from the photovoltaic cell.
According to Imperial, various studies have concluded that leaf-shaped photovoltaic cells can produce more than 10% additional power compared to traditional, rectangular solar panels. The latter typically loses nearly 70% of incoming energy to the environment. The team’s experiments found that approximately 590 W/m2 of heat was removed from the cell with the leaf shape, which decreased its temperature by nearly 26°C under an illumination of 1000 W/m2. Cell efficiency resultantly increased by almost 13.6%.
Besides the obvious advantage of increased efficiency and power, leaf-shaped photovoltaic cells have other benefits as well. These photovoltaic cells will change the future!
“Implementing this innovative leaf-like design could help expedite the global energy transition, while addressing two pressing global challenges: the need for increased energy and freshwater.” – Professor Christos Markides, Head of Clean Energy Processes Laboratory, and author of the study.
Generating power and so much more
The study abstract indicated that the hybrid multi-generation leaf-shaped photovoltaic cell is engineered from environmentally friendly, cost-effective, and easily accessible materials. This leaf-shaped photovoltaic design will eliminate the need for control units, expensive porous materials, fans, and pumps, saving consumers unnecessary effort and expenses. Leaf-shaped photovoltaic cells additionally supply thermal energy by using the recovered heat.
Their other advantages include:
- Adapting to numerous solar conditions
- Tolerating atmospheric temperatures
- Producing more than 40 billion cubic meters of clean water annually
- Increased overall solar usage efficiency of 74.5%
