Each solar cell is constituted by a transparent conductive layer, a first carrier conducting layer, a perovskite layer, and a second carrier conducting layer. By changing the ratio of area where the light is harvested for the perovskite layer, the photon absorption in the present invention therefore increases. Additionally, by changing the relevant position of the transparent conductive layer and the first carrier conducting layer, it renders the side surface of the transparent conductive layer be entirely covered by the first carrier conducting layer; thus, the usage of carriers is enhanced. The above two adoptions further enhance the efficiency of the module. Moreover, the insulating units are in the structure of distributed Bragg reflection and therefore can increase the photon absorption efficiency of the perovskite layer. Last but not least, the present invention further accomplishes the goal to manufacture a large-area perovskite solar cell module in order to meet the commercial demand.

The copper alloy nut and the corresponding screw are used in combination to bear higher pressure and do not fracture easily. Therefore, a small-structure high-thrust electric linear actuator can be realized. An electric linear actuator having a smaller volume is used to support the solar panel, so that small space is occupied, and transportation and use become more convenient.

A spectrum splitting, transmissive concentrating photovoltaic (tCPV) module is proposed and designed for a hybrid photovoltaic-solar thermal (PV/T) system. The system may be able to fully utilize the full spectrum of incoming sunlight. By utilizing III-V triple junction solar cells with bandgaps of approximately 2.1 eV, 1.7 eV, and 1.4 eV in the module, ultraviolet (UV) and visible light (in-band light) are absorbed and converted to electricity, while infrared (IR) light (out-of-band light) passes through and is captured by a solar thermal receiver and stored as heat. The stored heat energy may be dispatched as electricity or process heat as needed. The tCPV module may have an overall power conversion efficiency exceeding 43.5% for above bandgap (in-band) light under a standard AM1.5D solar spectrum with an average concentration ratio of 400 suns. Passive and/or active cooling methods may be used to keep cells below 110° C. while transmitting >75% of out-of-band light to the thermal receiver, which may attain thermal energy capture at temperatures as high as 500° C. or more. A transparent active cooling system may improve the CPV module efficiency by about 1% (absolute) relative to a passive cooling system by reducing the maximum cell working temperature by about 16° C.
