Advances in high-efficiency solar cells introduce photon management challenges, including the difficult texturization of flat surfaces and low photon utilization at short wavelengths. While bifacial crystalline silicon solar cells have a front pyramid structure and SiN layers reduce reflections, managing photons on the flat backside remains a challenge. To enhance light utilization, a soft nanoimprint technique was utilized to create pyramid micro-structured polyurethane films doped with europium (Eu) complex.

The cholera toxin B subunit (CTB), the heat-labile toxin B subunit from enterotoxigenic Escherichia coli (LTB), the Shigella toxin B subunit (STB), and the plant toxin ricin B subunit (RTB) were genetically linked to the islet autoantigens proinsulin (INS) and glutamic acid decarboxylase (GAD). The adjuvant-autoantigen gene fusions were transferred to a bacterial expression vector and the corresponding fusion proteins synthesized in E.
