Applicant:

THE ADMINISTRATORS OF THE TULANE EDUCATIONAL FUND [US]

CN_114631259_PA

Absstract of: US2022311378A1

A hybrid receiver for a concentrator photovoltaic-thermal power system combines a concentrator photovoltaic (CPV) module and a thermal module that converts concentrated sunlight into electrical energy and thermal heat. Heat transfer fluid flowing through a cooling block removes waste heat generated by photovoltaic cells in the CPV module. The heat transfer fluid then flows through a helical tube illuminated by sunlight that misses the CPV module. Only one fluid system is used to both remove the photovoltaic-cell waste heat and capture high-temperature thermal energy from sunlight. Fluid leaving the hybrid receiver can have a temperature greater than 200° C., and therefore may be used as a source of process heat for a variety of commercial and industrial applications. The hybrid receiver can maintain the photovoltaic cells at temperatures below 110° C. while achieving overall energy conversion efficiencies exceeding 80%.
