Abstract: A photovoltaic interconnect wire includes a conductive base strip with grooves provided thereon, and the grooves are linear and/or curved strip-shaped grooves (3) arranged obliquely to a longitudinal direction of the conductive base strip. An inclination angle of 15° to 75° is present between each linear strip-shaped groove and the longitudinal direction of the conductive base strip, and between a tangent line of any point on the curve of a curved-shaped groove and the longitudinal direction of the conductive base strip. The photovoltaic soldering strip increases an output power of a solar cell assembly by increasing the total reflection proportion. It also ensures soldering fastness by adjusting flat regions of the base strip. Effective cross section loss of the conductive base strip is reduced by adjusting the angle of each groove, so as to minimize the confluence efficiency loss of the soldering strip.

Abstract: A dual-spectrum intelligent cooking and baking machine without oil fume includes a housing, a top cover, an inner cylinder with heat preservation, an inner cooking and baking machine and a control circuit. An upper heater is disposed on the inner top surface of the top cover, and a lower heater is disposed on the inner undersurface of the inner cylinder with heat preservation. The upper heater and the lower heater are optical heaters. An insulating layer with light and heat penetration is disposed on the lower heater. The inner cooking and baking machine is a pan, a stockpot or a barbecue net rack. The pan or the stockpot is disposed moveably on the upper surface of the insulating layer with light and heat penetration. The barbecue net rack is disposed moveably over the insulating layer with light and heat penetration and is connected with the motor by the coupling device.
