Reaching optimal efficiencies using nanosized photoelectric devices
نویسنده
چکیده
Understanding and controlling the mechanisms that determine the efficiency of photoelectric devices is of fundamental importance in the quest for efficient and clean sources of energy. Thermodynamically speaking, these devices are driven by the temperature difference between a hot reservoir sun, temperature Ts and a cold reservoir earth, ambient temperature T . Therefore, like any heat engine, the efficiency at which the conversion of radiation into electrical energy takes place has a universal upper bound given by the Carnot efficiency1 c = 1 − T/Ts. 1
