Claim 14:
15. A system, comprising:
a roof deck; and
a plurality of photovoltaic modules installed on the roof deck,
wherein each of the photovoltaic modules includes
a frontsheet,
an encapsulant,
wherein the encapsulant includes an upper layer, and

a plurality of solar cells,
wherein the plurality of solar cells is encapsulated by the encapsulant,
wherein the plurality of solar cells includes at least a first solar cell, a second solar cell, and a third solar cell,
wherein the upper layer of the encapsulant is above the first solar cell, the second solar cell, and the third solar cell;

light-scattering material in the upper layer of the encapsulant,
wherein the light-scattering material includes a first light-scattering material and a second light-scattering material,
wherein the first light-scattering material is above the first solar cell,
wherein the first light-scattering material has a first light-scattering value as measured in accordance with an ASTM E430 standard,
wherein the second light-scattering material is above the second solar cell,
wherein the second light-scattering material has a second light-scattering value as measured in accordance with the ASTM E430 standard, and
wherein the second light-scattering value is different than the first light-scattering value.
