The power conversion efficiency of Perovskite Solar Cells (PSC) has been improved rapidly in the last three years. After the power conversion efficiency has achieved over 20% recently, the improvement of the stability of perovskite solar cells has become the main challenge for both industrial and academic researchers. Dyesol is focusing on the stability improvement and commercialization of carbon based PSC. We have achieved >90% performance retention after 1000 hour light soaking at 1 sun as shown in the figure below. This work systematically studied the stability of carbon based PSC under light soaking, thermal stress at different temperatures, and thermal cycling between 40oC and +85oC; and the effects of various factors on the stability of carbon based PSC including encapsulation materials/methods, cell configurations, and light spectra. Detailed data will be reported, presented and discussed in terms of degradation mechanisms. Dyesol also achieved >9% 10 cm x 10 cm carbon based perovskite solar modules. Performance of modules prepared by industrially scalable processes will also be presented. .
