摘要： To provide a cover glass for a solar cell module which can sufficiently maintain the power generation efficiency of a solar cell module, even when a design is imparted to the entire surface of the cover glass so as to make solar cells be invisible from the outside, and a solar cell module.
To provide a cover glass 14 to be bonded on light-receiving surfaces 16A and 16B of solar cells 16 via an encapsulant material 18, which has a visible transmittance of from 0% to 60% and an average infrared transmittance of from 20% to 100%, which is a value calculated by simply averaging transmittances at 5 nm intervals in an infrared region at a wavelength of from 780 nm to 1,500 nm.

摘要： The present invention pertains to a sulfide based solid electrolyte that is for use in a lithium ion secondary battery and that includes an argyrodite-type crystal structure containing Li, P, S, and Ha. The Ha is at least one kind selected from the group consisting of F, Cl, Br, and I. In a Raman spectrum, a peak is present in at least one selected from the group consisting of 140-170 cm -1 , 205-235 cm -1 , and 460-490 cm -1 . In a DSC curve, an endothermic peak is not present in the range of 70-160°C.
