An efficient organic inverted solar cell with AnE-PVstat:PCBM active layer and V2O5/Al anode layer

WOS: 000330489900009An inverted organic solar cell, which is based on anthcene-containing poly (p-phenylene-ethynylene)-alt-poly(p-phenylene-vinylene) (PPE-PPV) polymer (AnE-PVstat) and phenyl C-61 butyric acid methyl ester (PCBM), was fabricated with Titanium dioxide (TiO2) electron transport layer and V2O5/Al anode layer. In this study, we have investigated the effect of V2O5 thickness on solar cell efficiency. Power conversion efficiency of 3.26% has been achieved for 15 nm V2O5 layer. The lifetime of the cell was investigated using ISOS-L-1. The test indicated that the durability of the solar cell, which is designed in ITO/TiO2/AnE-PVstat:PCBM/V2O5 (15 nm)/Al configuration, is 99% under standard solar irradiation of 100 mW/cm(2) (AM 1.5 G) at ambient conditions for 24 h.

Round robin performance testing of organic photovoltaic devices

This study addresses the issue of poor intercomparability of measurements of organic photovoltaic (OPV) devices among different laboratories. We present a round robin performance testing of novel OPV devices among 16 laboratories, organized within the framework of European Research Infrastructure Project (SOPHIA) and European Energy Research Alliance (EERA). Three types of OPVs with different structures, dimensions and encapsulations are studied and compared with reference Si solar cells certified by accredited laboratories. The agreement of the measurements of these among different laboratories is analyzed by focusing on testing procedures, testing equipment and sample designs. A number of deviations and pitfalls are revealed and based on the analyses, a set of recommendations are suggested for improving the agreement among the measurements of such OPV technologies.European Commission's FP7 programme; European Energy Research Alliance (EERA); EUDP; UK Department for Business, Innovation and Skill
