Abstract: A luminaire includes a lamp holder, a lamp cover and a plurality of first light-emitting modules. The lamp holder has a top surface, a plurality of protrusions protruding upwardly from the top surface. Each of the protrusions has an inclined surface. The lap cover is connected to the lamp holder, and covers the top surface and the inclined surfaces. Each of the first light-emitting modules includes a first light-emitting element. The view angle of the luminaire can be increased due to disposition of the first light-emitting elements on the inclined surfaces of the protrusions. Furthermore, since the first light-emitting elements are disposed on the protrusions, heat can be dissipated easily from the first light-emitting elements.

Abstract: Disclosed is an apparatus and method for generating inverted organic solar cells and which required no electron selective layer, were fabricated and their power conversion efficiency was found to improve irreversibly with post-processing light soaking for a period. X-Ray photoelectron spectroscopy characterization further revealed segregation in surface composition at the interface and was found to explain the current density-voltage measurements. In addition, the light soaked devices were found to exhibit an extended lifetime as compared to conventional devices. Since no electron selective layer was required, light soaking may be considered as a cost-effective method to achieve efficient inverted organic solar cells.
