Shading distributed solar cell

By dispersing power generation loss due to shadows such as needles in multiple cells and increasing light reception efficiency, the power required for functions such as GPS satellite signal reception is secured. In addition, it has become possible to use a three-dimensional dial with low transmittance, and to design larger hands and hour characters.
