Heliatek GmbH, a Germany-based developer of solar PV technology, says it has set a new efficiency record for organic solar cells after Fraunhofer ISE CalLab certified a cell efficiency of 9.8% for a 1.1 square-centimeter tandem cell manufactured with a low-temperature deposition process.
This new record makes the third time in a row that Heliatek has set a world record for efficiency in the field of organic photovoltaics, the company adds. One year ago, Heliatek set a world record for efficiency of 8.3% for an active surface of 1.1 square centimeters.
The new cell construction is planned to gradually be integrated into Heliatek's manufacturing process after the scheduled start of production in the second half of 2012. Heliatek's in-house measurements have shown that scaling up the record-breaking cells to a panel with a size factor of more than 120 results in an efficiency over 9% for the active module area, the company adds.
