Ozioma Ozioko, a doctoral student at Rensselaer Polytechnic Institute, is on a mission to give her home country of Nigeria — and the rest of the world — ready access to solar energy. “Growing up, the power supply was very unstable. Sometimes we could go for a week without power. I remember my brothers and I doing our homework by the light of a kerosene lamp,” Ozioko said. “Nigeria has abundant solar energy resources, but the cost-effective utilization of these resources is a challenge. I want to change that.”
