Welcome to the Collins Group at Washington State University. Our research is highly interdisciplinary, straddling physics, materials science, electrical engineering and chemistry. We specialize in developing and using synchrotron X-ray techniques to investigate carbon-based materials designed to have novel optoelectronic properties. We strive to understand how interactions of organic molecules and polymers in aggregate and at interfaces govern the creation, transport, and annihilation of excited and charged states that result in power generation/storage, illumination, sensing and information processing.
Obaid Alqahtani’s Solar Cell Work Published in Advanced Energy Materials
Obaid Alqahtani’s work on structure-property relationships in small molecule organic solar cells (SM-OSCs) has been officially published online at Advanced Energy Materials. SM-OSC devices convert sunlight into power like commercial solar panels, but this new technology could significantly lower the cost of solar power because it can be printed from inks in a roll-to-roll newspaper fashion, is light-weight and flexible, and is made from earth-abundant, non-toxic materials.
Alqahtani’s work explains how the performance of SM-OSCs depends on the details of … » More …Read Story
Terry McAfee joins as Postdoctoral Researcher
Terry McAfee has joined the Collins Research Group as postdoctoral researcher. He obtained his PhD in physics from North Carolina State University under Professor Harald Ade. His thesis was titled “Characterization and control of morphology in organic photovoltaic devices.” Recently, he completed postdoctoral work at Tulane University under Professor Wayne Reed developing an Automatic Continuous Online Monitoring of Polymerization (ACOMP) system. Terry joins the Collins group to develop a new Environmental Resonant Soft X-ray Scattering instrument which will enable in-situ/in-operando structural measurement of organic materials.Read Story
