“…This is not completely unexpected. As anticipated by the energetic analyses, an efficient heat dissipation at the cold TEG side is essential to grant usable temperature differences across the TE stage while keeping the PV stage at a relatively lowtemperature, as also independently confirmed by Ismaila et al 55) Heat exchanger technologies remain largely based on (micro)mechanical machining, leading to high costs per dissipated power density, and their impact on the cost of thermoelectric devices (harvesters and coolers) also hampers many other applications. For an extensive analysis of the economic impact of HX costs on non-PV applications the reader may refer to the extensive studies carried out by Hendricks and co-workers 56,57) on this topic.…”

The possibility of recovering heat released by photovoltaic (PV) solar cells into electric power by using thermoelectric generators has attracted a remarkable research effort over the last two decades. Views and results are not fully converging, however, ranging from overoptimistic estimates of power gains to fully negative opinions about the convenience of hybridization. Aim of this paper is to review both energetic and economic profitability of photovoltaic-thermoelectric hybridization, as both issues are to be considered in the design of hybrid solar harvesters. It will be shown how the PV material rules the total system efficiency and its economic competitiveness compared to standard PV modules. Marginal opportunities are reported for rooftop concentrated solar harvesters. Yet, hybridization may leverage novel PV materials, currently not considered due to their lower efficiency compared to polycrystalline silicon. Much more significant is instead the window of opportunity when thermoelectric generators are coupled to perovskite solar cells.
