Breakthrough solar panel efficiency.
Thanks to swiss and american researchers perovskite solar cells as compared to the silicon cells that are used predominantly today have seen some major breakthroughs in the past two years.
Solar panel efficiency is a measure of how much sunlight that hits the surface area of a solar panel is converted into usable electricity.

What you need to know.
Mono and poly solar panels commonly used in homes today operate between a 13 22 efficiency rating.
The shockley queisser limit marks the maximum efficiency for a solar cell made from just one material and for silicon this is about 30.
Oxford pv perovskite solar technology has been certified by the national renewable energy laboratory nrel in california as reaching 28 efficiency beating its world record for perovskite solar cell efficiency of 27 3.
Given the same amount of sunlight shining for the same duration of time on two solar panels with different efficiency ratings the more efficient panel will produce more electricity than the less efficient panel.
However combining six different materials into what is.
With higher efficiency government incentives and improved technology the prices of residential solar panels continued to plummet particularly over the past decade.
The two studies published in nature energy and nature photonics will transform the efficiency and significantly reduce the cost of producing solar cells scientists say.
Silicon solar cells that are commonplace on the market right now achieve an average conversion efficiency of around 20 per cent.
The result will be a solar panel that can generate 20 percent efficiency while still being one of the lowest cost options on the market.
With this absorber material the solar cell breaks the 10 benchmark efficiency barrier.
Oxford pv s cutting edge research and commercialization expertise has led to a world record in efficient solar panels.
What are the price trends for solar panels.
Using these stacked perovskite silicon variations however would potentially see an efficiency of 27 7 per cent.
So if a solar panel has an efficiency rating of 15 that means 15 of the sunlight that hits the solar panels will be converted into electricity.
