Abstract: According to one aspect, there is provided a solar energy converter, including: a lens; a base plate having a first surface that faces the lens and a second surface that is opposite to the first surface; and a solar cell sandwiched between the lens and the base plate, wherein both the lens and the base plate are each provided with at least one channel for fluid for cooling the solar cell. Also contemplated is provision of at least one fin on both the lens and the base plate for cooling the solar cell. According to a second aspect, there is provided a method for cooling a solar energy converter having a lens, a base, and at least one solar cell sandwiched between said lens and said base plate, the method comprising the step of: cooling the at least one solar cell on two opposing sides.

Abstract: An ophthalmic device for aiding in the accurate dispensing of a medicating substance into an eye, said device comprising an elastic eye cup (4) having an open end and an aperture (8) at an opposite end and a jacket (6) for the eye cup, said jacket being of higher rigidity. The periphery of the open end is adapted to receive and secure the nozzle associated with an eye drop dispenser. The jacket one having a substantially similar shape to the eye cup and having a through-hole sufficient to allow for the secure fitting of said eye cup jacket around a substantial portion of the eye cup, such that the aperture remains unobstructed.
