〈div〉〈p〉Spectral grain and loss (spectral gain&loss) of several-type PV technologies (amorphous silicon (a-Si), perovskite (perov), CdTe, CuInSe〈sub〉2〈/sub〉 (CIS), multi-crystalline silicon (mc-Si), single-crystalline silicon back-contact (BC), single-crystalline silicon (sc-Si), and heterostructure-with-intrinsic-thin-layer (HIT)) was investigated in different places (Kusatsu city, Tsukuba city, and Miyazaki city in Japan) in a year. Spectral gain&loss is defined as a ratio of short-circuit current (〈em〉I〈/em〉〈sub〉〈em〉SC〈/em〉〈/sub〉) corrected by solar irradiance (〈em〉Irr〈/em〉) for PV module at an average photon energy (〈em〉APE〈/em〉) to its 〈em〉I〈/em〉〈sub〉〈em〉SC〈/em〉〈/sub〉 under standard test condition. The blue-rich spectra with 〈em〉APE〈/em〉 over 1.88 eV yield spectral gain (spectral gain&loss over 1) for CdTe, perov, and a-Si PV technologies owing to large band-gap energy (〈em〉E〈/em〉〈sub〉〈em〉g〈/em〉〈/sub〉) values of 1.47, 1.60, and 1.80 eV, respectively. On the other hand, red-rich spectra with 〈em〉APE〈/em〉 below 1.88 eV lead to spectral gain for CIS, mc-Si, BC, sc-Si, and HIT PV technologies with smaller 〈em〉E〈/em〉〈sub〉〈em〉g〈/em〉〈/sub〉 values of 1.21, 1.13, 1.17, 1.16, and 1.09 eV, respectively. Moreover, since average 〈em〉APE〈/em〉 values in Kusatsu city, Tsukuba city, and Miyazaki city are 1.931, 1.900, and 1.899 eV, respectively, a-Si, perov, and CdTe PV technologies are suitable in term of spectral response. The spectral gain&loss of PV modules compared with sc-Si PV module is moreover discussed.〈/p〉〈/div〉
