PROBLEM TO BE SOLVED: To provide a polymer sheet for a solar cell, which achieves both designability and scratch resistance.SOLUTION: The polymer sheet for a solar cell has, on a polymer support, a first polymer layer which contains a polymer having a refractive index of 1.55 or less and fine particles having a refractive index of 1.8 or more, and a second polymer layer which is laminated on the first polymer layer and contains a polymer having a refractive index of 1.55 or less and fine particles having a refractive index of 1.8 or more. The second polymer layer is an outermost layer. The ratio W/Wof the content W(unit: g/m) of the fine particles in the first polymer layer to the content W(unit: g/m) of the fine particles in the second polymer layer is 5.0-50.0. |
