When considering just the surface normal method, the non-cylindrical parts (2,3,8,9) produce similar to slightly higher efficiencies than the square LSC, which is in line with results of previous studies. The cylindrical parts have higher efficiencies, around 15-20%, which is also supported by experimental and simulated results. Note that while the parts were all standardized to have the same incident surface area, the variation in efficiency, especially for the triangle and Leaf Roof parts, could be due to different gains between parts.
