The dihedral angle between planes a and b obtained by molecular orbital calculation was 89.9°. Hence, the two planes are perpendicular to each other. The structure in which the two planes form a right angle is the most stable. The molecular orbital calculation was performed as below. All the...
Research results reveal that the light escape rate of the device is 5.36% at an incidence angle of 12°. At a velocity of 1.5 m/s, the maximum air temperature of the outlet can reach 55.6 °C, and the total output power of the solar cells is 474.4 W. The variation of the total ...
