A method of diagnosing malfunctioning of a bypass diode in a solar photovoltaic battery system is provided. The method may include: collecting solar photovoltaic battery operation information indicating a solar photovoltaic battery operation state, from a signal of a solar photovoltaic battery detection unit, while maximum power point tracking control is performed with the solar photovoltaic battery system in operation; and determining whether or not the bypass diodes based on the collected solar photovoltaic battery operation information.

A flexible thermoelectric element and a method for manufacturing the same is provided. The thermoelectric element is disposed between a high temperature portion and a low temperature portion and includes a plurality of p-type materials and n-type materials formed at a predetermined interval and is folded at sections of the p-type materials and sections of the n-type materials to form folding components. An insulating filler is coated between the p-type materials and the n-type materials that are folded. A module is formed by folding the flexible thermoelectric element, and separate cutting and alignment of the thermoelectric element are omitted at portions that contact with the high and low temperature portions.

A system for using a solar cell includes a solar cell module configured to convert sunlight into electric energy, an engine operating circuit configured to convert mechanical energy generated by an engine operation of a vehicle into electric energy and provide the electric energy, a solar cell circuit configured to provide the electric energy generated through the solar cell module, a battery configured to be charged by electric energy provided by the solar cell circuit or the engine operating circuit, a load, and a controller of a vehicle. The controller is configured to control a connection of the circuits to the battery or to the load depending on a measured state of charge of the battery, driving of the vehicle, and acceleration of the vehicle. A method for using a solar cell is also disclosed.

System and method for using solar cell

A hybrid type roof panel of a vehicle has a solar cell mounted on the roof panel, in which two types of solar cell modules are simultaneously mounted, in order to provide a sense of openness of the roof panel and simultaneously maximize performance of the solar cell. In the roof panel covered with roof glass, two types of solar cells are disposed over an entire area of the roof glass in a hybrid manner, including: a first solar cell having transparent characteristics disposed in a center of the roof glass; and a second solar cell having better photovoltaic performance than the first solar cell disposed in an edge part of the roof glass.
