SOLAR POWER GENERATOR FOR WINDOWS

摘要

The present invention relates to a solar battery for windows. The solar battery for windows comprises: a photovoltaic power generation layer which is arranged on a glass layer used as a window of a vehicle and generates a current by receiving solar light which passes through the glass layer; and a protective film layer which protects the photovoltaic power generation layer. The solar battery for windows is arranged on the protective film layer. The photovoltaic power generation layer includes: a transparent conductive film which is arranged on the glass layer; a transparent solar battery active layer which is arranged on transparent conductive film; and a transparent counter electrode which is arranged on the transparent solar battery active layer. The transparent solar battery active layer further includes: finger lines which are extended along a longitudinal direction of the glass layer and transmit the current generated in the transparent solar battery active layer, wherein the finger lines are repeatedly arranged with a constant spacing between them; and a current collecting electrode including bus bars which connect one end portions of the finger lines with one another to collect the current transmitted through the finger lines, and transmit the collected current. When photovoltaic power generation is performed by using a near infrared-infrared (NIR-IR) range from an infrared ray constituting 45% of the solar light, a transparent solar battery is applied to a window portion. Therefore, a current collecting effect can be maximized while maintaining transmittance by using the current collecting electrode preventing losses in resistance and an output, as an applied area of the transparent solar battery is increased.
