The effects of the necessary front electrode in near-field ultrathin resonant thermophotovoltaic cells are analyzed.Absorption inside the transparent conducting electrode limits the power level that can be efficiently converted to electricityand several electrode materials are compared in performance. The assisting grid of metallic fingers suppresses thermalradiation from the emitter in its region across from them, leading to reduced shading losses and wider optimal fingers thanusually associated with far-field photovoltaic cells. Promising performances are predicted, reaching 24% at 900K and 48%at 2100K.
