Love it, indeed
Really good solution
Same as old one
The old one was better
This is a new option

A voltage breakthrough with perovskite solar edges closer to commercialisation

RATE THIS! +7
Posted in Hardware on 5th Jul, 2018 08:37 PM by Alex Muller

A new technique has produced the highest performing inverted perovskite solar cell ever recorded. A team of researchers from Peking University and the Universities of Surrey, Oxford and Cambridge detail a new way to reduce efficiency loss in perovskite solar cells.

 

The team created a technique called Solution-Process Secondary growth (SSG) which increased the voltage of inverted perovskite solar cells by 100 millivolts, reaching a high of 1.21 volts without compromising the quality of the solar cell or the electrical current flowing through a device. They tested the technique on a device which recorded a PCE of 20.9 percent, the highest certified PCE for inverted perovskite solar cells ever recorded.

 

Researchers are still working towards increasing efficiency and stability, prolonging lifetime and replacing toxic materials with safer ones. Researchers are also looking at the benefits of combining perovskites with other technologies, like silicon for tandem cells.

 

The hope is to bring perovskite solar power down to pennies per watt. The average module sold to a utility scale project in 2017 was about 35 cents, it will fall to 32 cents in 2018 and 31 in 2019.
