Cutting Edge Perovskite Solar Cell Technology.
When it comes to solar cells and panels, efficiency makes all the difference. By efficiency I mean, not the efficiency of producing a finished solar panel, which also is a huge factor in the cost to consumers, but the efficiency of the solar panel in turning light into electricity.
The top end of panel efficiency on the market today is about 19.7 %. This is not the overall percentage efficiency but just the efficiency for that panels. You still have the power losses from the wiring to the inverters, the inverter losses themselves and the wiring to point of use. These last components have a pretty much fixed percentage loss ( except for the newest inverters) so any improvements to panel efficiencies will impact the overall system.
If researchers could design a cost effective solar cell that has a much higher efficiency of conversion, the cost per kwatt of installed solar power systems would also decrease significantly.
The Perovskite Company, which is considered as a leader in the field of perovskite solar cell development, have just announced a new, certified, world record for its perovskite solar cell.
Oxford PV’s 1 cm2 perovskite-silicon tandem solar cell has achieved a 27.3% conversion efficiency, certified by the Fraunhofer Institute for Solar Energy Systems ISE. This exceeds the 26.7% efficiency world record for a single-junction silicon solar cell.
Frank P. Averdung, Chief Executive Officer at Oxford PV commented,
This result further validates the ability of perovskite to enhance the performance of silicon based photovoltaics. Continuing to improve the performance of photovoltaics is fundamental for sustaining the growth of solar generated electricity.
Dr Chris Case, Chief Technology Officer at Oxford PV added,
We are continuing to push our perovskite-silicon solar cell technology with a roadmap that extends beyond 30% efficiency, driving the world towards an all-electric future. Oxford PV counts on the support of development partners, suppliers and customers to deliver its perovskite solar technology.
Today’s record demonstrates the considerable progress the company has made in driving its perovskite solar cell solution closer to commercialisation. Oxford PV is in the process of scaling its perovskite-silicon solar cell technology from the lab to high volume manufacturing. The company is producing commercial sized 156 mm x 156 mm perovskite-silicon solar cells, at its 17,000 m2 industrial pilot line in Germany, for validation by its development partner – a major manufacturer of silicon solar cells and modules.
