On March 20, the British journal Nature Energy published an important research result online, reporting the first silicon solar cell
with a light conversion efficiency of more than 26%.
The cell has been certified to achieve a conversion efficiency of 26.
3%, indicating that the efficiency of silicon solar cells has reached an all-time high, and more more efficient silicon solar panels will be available
in the future.
According to the Nature Energy article, by 2050, photovoltaic power will bear more than
20% of the global primary energy demand.
However, at present, the cost of solar power generation is still high compared with other energy sources, and reducing the cost of power generation is one of the main development goals of related enterprises and organizations around the world, so improving the photoelectric conversion rate of silicon solar cells has become a key step
in the further deployment of photovoltaic power.
The theoretical efficiency of silicon solar cells is about 29%, because in the energy of incident light, 20% to 30% is transmission loss, about 30% is quantum loss, and about 10% is carrier recombination, surface reflection loss and series resistance loss
.
The researchers proposed a new method to achieve the theoretical conversion efficiency limit of silicon solar cells - 29.
1%, which opened the door to
achieve the goal of efficient conversion of solar power generation and cost reduction.
The research team emphasizes that although the study has broken the world's record for the photoconversion efficiency of silicon solar cells to date, further research
is needed to assemble individual cells into commercially viable solar panels.
