“…For instance, experimental total system efficiencies as high as 65.1% [242], theoretical heat transfer fluid (HTF) outlet temperatures as high as 196 1C [247], costs as low as 2.37 $ W e À 1 [237], levelized energy (electrical and thermal) costs as low as 8.7 c€ kWh À 1 [259], and energy and greenhouse gas payback periods as low as one year [258] have all been reported in the literature. Several review articles on PVT technology [2][3][4][5][6][7][8][9][10]230,231,[297][298][299][300] and CPV technology [11][12][13][14][15][16][17] already exist in the literature. One review article on low-concentration CPVTs [232] is found in the literature.…”
