The College of Ottawa’s laboratory in photonics and renewable power has developed a brand new method to quantify photo voltaic power generated by bifacial photo voltaic panels, the double-sided photo voltaic know-how that’s anticipated to satisfy the rising world power calls for sooner or later.
The analysis was revealed within the journal Joule and describes a detection method that improves the analysis of bifacial panels indoors by considering exterior results corresponding to snow, grass, and soil. It will permit for constant efficiency testing of bifacial photo voltaic panels indoors, which can precisely symbolize how the panels function open air.
With bifacial photovoltaics predicted to achieve greater than 16% of worldwide power demand in 2050, the SUNLAB technique will enhance worldwide requirements for measuring the system, which presently doesn’t distinguish between land cowl.
Our proposed detection technique, the scaled rear irradiance technique, is an improved technique for indoor and modeling bifacial units representing out of doors environmental situations..

Erin Tonita does analysis beneath Professor Karin Hinzer, whose analysis group explores new methods to make use of photo voltaic power.
Incorporating this new technique into future bifacial requirements will present a constant methodology for testing bifacial panel efficiency beneath floor situations together with snow, grass, and soil, equal to a worldwide selection. gentle situations.

The research of changing photo voltaic power into electrical energy utilizing semiconducting supplies corresponding to silicon is called photovoltaics. The semiconducting materials of bifacial photo voltaic panels is sandwiched between two sheets of glass to allow the gathering of daylight on either side, with one aspect often inclined in the direction of the solar and the opposite in the direction of the bottom.
The extra gentle obtained by bifacial photo voltaic panels within the background offers a bonus over standard photo voltaic panels, with producers claiming a 30% improve in manufacturing over conventional photo voltaic panels. Bifacial photo voltaic panels are additionally extra sturdy than common panels and may produce electrical energy for over 30 years.
“The implementation of this technique to worldwide requirements for such panels could make predictions of outside bifacial panel efficiency inside 2% of absolute.,” stated Tonita, who anticipates that the advantages of this technique embody:
- Allows comparisons between present and rising bifacial applied sciences.
- Increasing the deployment of photo voltaic panels in non-traditional markets.
- Growth of bifacial panel manufacturing datasheets.
- Efficiency enchancment by means of floor cowl particular design optimization.
- Decreasing funding threat in bifacial panel deployment.
This method is especially necessary because the penetration of renewable power will increase in the direction of a net-zero world, with bifacial photovoltaics projected to contribute over 16% of the worldwide power provide by 2050, or about 30,000 TWh per yr.

Karin Hinzer is the founding father of SUNLAB, and is the College Analysis Chair in Photonic Gadgets for Power.
Hinzer, whose SUNLAB investigators partnered with Arizona State College for the analysis, concluded, “It extends the present Worldwide Electrochemical Fee requirements for bifacial photo voltaic panel measurements, allows correct comparability of bifacial panel applied sciences, application-specific optimization, and the standardization of bifacial panel energy rankings..”
