The invention relates to a manufacturing method of an organic solar cell. The measurement circuit includes a thermistor network to compensate for the effect of changes in ambient temperature to the resistance of the active element. In an assembly, the passive fan blade is mounted via a bearing assembly and mounting hardware onto a hub connected to a bracket. In addition, the top load is coupled to the feed post and the shorted post and is configured along orthogonal minor and major axes of the top load to have a width along the minor axis and a length along the major axis that exceeds the width. The TFT substrate has a display region defined to include the pixels and a non-display region formed outside the display region.
