The slope of the V-I curve for a solar cell, given in degrees (66.1°), can be converted into the resistance value by first converting the angle into radians and then taking the tangent of that angle, as the slope in a V-I curve represents resistance (R = V/I). The tangent of 66.1° gives the resistance value. Tan(66.1°) ≈ 2.246, which rounds to approximately 2.2 ?.
