oxford pv at 15.4%, page-2

Dyode,
Having the advantage of an UK based company and used cheaper materials than TiO2 ?. Oxford PV could be a serious contender of DSC in the UK one would think..

They did not say the testing conditions adopted to obtain the 15.4% efficiency..


"A significant step forward in the scale-up and commercialisation of Oxford Photovoltaics (Oxford PV) new photovoltaic technology has been achieved by establishing a new high of 15.4% efficiency for its perovskite solar cells.....

Importantly, the new test results have been achieved without using Mesoporous Titanium Dioxide (TiO2) as a semiconductor, making for a more efficient conversion of energy with enhanced stability.

This improvement, allied to the large area manufacturing process development and the use of abundant and extremely low-cost materials, is enabling Oxford PV to overcome the challenges of reliability, performance and cost often associated with PV solutions."
