Heliatek’s Organic Solar Cells Join PV Firms Setting Records in Efficiency: We've been keeping a tally of reco...

We've been keeping a tally of record setting solar cell and module achievements and are now adding Heliatek's record for organic solar cells . It's a champion cell on a small area but it has achieved 10.7 percent efficiency. The question remains -- can organic solar cell technology be successfully commercialized in an unforgiving solar market dominated by crystalline silicon and First Solar ? Heliatek of Dresden, Germany thinks so. The efficiency value for the 10.7 percent champion cell would be about 9.0 percent when deposited on a flexible substrate. Organic solar cells (OSCs) are sometimes referred to as third-generation solar technology, after crystalline silicon and thin-film solar technology. OSCs can be divided into two categories: polymer-based (large molecules) and oligomer-based (small molecules). Heliatek uses vacuum deposition of very homogenous layers of small...
