Abstract:
A photovoltaic cell structure includes a substrate, a metal layer, a p-type semiconductor layer, an n-type semiconductor layer and a transparent conductive layer. The substrate has a rough surface. The metal layer may include molybdenum and be formed on the rough surface. The p-type semiconductor layer is formed on the metal layer and may include CIGSS, CIGS, CIS, or compound of two or more of copper, selenium, sulfur. The n-type semiconductor layer is formed on the p-type semiconductor layer thereby forming a rough p-n junction surface. The n-type semiconductor layer may include CdS. The transparent conductive layer is formed on the n-type semiconductor layer. In an embodiment, the roughness Ra of the rough surface is between 0.01 to 100 μm.

Abstract:
A projection lens provided is for projecting an image beam. The projection lens is disposed on a transmission path of the image beam and includes a first group of lenses and a second group of lenses. The first group of lenses includes a first spherical lens and a first aspheric lens. After the image beam passes through the first group of lenses, an intermediate image is formed between the first group of lenses and the second group of lenses, in which the first aspheric lens is the lens in the first group of lenses closest to the second group of lenses. A projection device using the projection lens is also provided. The projection device further includes a planar reflector on the transmission path of the image beam.

The light source provides an illumination beam. The light valve is capable of converting the illumination beam to the image beam. The projection lens has a first optical axis. The image capture lens has a second optical axis. The first optical axis and the second optical axis are collinear. The dichroic unit is disposed between the projection lens and the image capture lens. The image sensor is disposed on a light path of the sensing beam.
Abstract:
An illumination system includes a first light source, a first rotation wheel, a first phosphor element, and a light combining element. The first light source is capable of emitting a first color beam. The first rotation wheel is disposed on a transmission path of the first color beam and includes a first transmissive region and a first reflective region. The first transmissive region is capable of allowing the first color beam to pass through so as to form a first color transmissive beam. The first reflective region is capable of reflecting the first color beam to form a first color reflective beam. One of the first color transmissive and reflective beams excites the first phosphor element to form a second color beam. The light combining element combines the second color beam and a beam originating from the other one of the first color transmissive and reflective beams.

A hinge includes a base, an arm, a mounting member, a hinge spring, a fixing pin member, and a damping device. Two ends of the arm are pivotably connected to the base and the mounting member, with the hinge spring exerting elastic force on the base and the arm. The damping device is mounted in the base and includes a fixed seat mounted in the base, a sliding block movably received in the fixed seat, a damping member mounted between the sliding block and the fixing pin member and abutting the base, and an elastic element. The sliding block includes a front portion facing the arm and a rear portion connected to the elastic element pressing against the fixed seat.

A hinge includes a base, an arm, and an elastic element. The base includes a recessed body having a rear wall with a supporting portion. The arm includes a pivotal portion and two cam portions. A first pin section of a fixing pin member is extended through the pivotal portion and connected to the base. The elastic element includes two front elastic portions, a rear elastic portion, two intermediate portions each interconnected to one of the front elastic portions, and two extensions each interconnected between the rear elastic portion and one of the intermediate portions. The front elastic portions press against the cam portions. The intermediate portions are connected to the base by a second pin section of the fixing pin member. The rear elastic portion abuts the supporting portion of the rear wall.
Abstract:
A photovoltaic cell structure includes a substrate, a metal layer, a high resistivity layer, a p-type semiconductor layer, an n-type semiconductor layer and a transparent conductive layer. The metal layer may include molybdenum and be formed on the substrate to be a back contact metal layer of the cell. The high resistivity layer (e.g., V2O5) is formed on the metal layer. The p-type semiconductor layer is formed on the high resistivity layer and may include compound of CIGS or CIS. The n-type semiconductor layer (e.g., CdS) is formed on the p-type semiconductor layer, thereby forming a p-n junction. The transparent conductive layer is formed on the n-type semiconductor layer.

Abstract:
A vertical probe device includes two guide members arranged in a stack manner and defining therebetween an accommodation chamber, a probe holder plate disposed between the guide members, and a plurality of probes inserted through the guide plates and the probe holder plate in such a manner that the probes are flexible within the accommodation chamber. One of the guide plates has at least one through hole. The probe holder plate is slightly moveable in horizontal and vertical directions but fixable to one of the guide plats under a force applied through the at least one through hole to the probe holder plate while the other of the guide plates is removed, thereby preventing damage of the probes or movement of the probes during a maintenance work.
