The ONE lab focuses on solution-processed thin-film devices, including organic and perovskite solar cells, thin-film transistors (OTFTs), and large-volume manufacturing of photovoltaic cells and modules through high-speed printing on flexible substrate. The lab has expertise on rapid photonic annealing and sintering, and nanofabrication with electron-beam lithography for making nanoimprint molds and nanoimprint lithography for easy duplication of nanopatterns. The ONE lab has full set up solar cell fabrication and characterization tools, such as glove box fabrication system with built-in thermal evaporator, solar simulator, quantum efficiency testing kit, probe station, and semiconductor parameter analyzer.
