Abstract: The present disclosure provides a thin film solar cell and a manufacturing method thereof. The thin film solar cell includes a transparent substrate and a photovoltaic unit disposed on the transparent substrate and facing a display module. The photovoltaic unit includes a front electrode disposed on the transparent substrate, a light absorption layer disposed on the front electrode, and a back electrode disposed on the light absorption layer. The thin film solar cell further includes a metal auxiliary electrode and an insulating layer. The insulating layer covers the back electrode and the light absorption layer, and extends to be in contact connection with the front electrode. The metal auxiliary electrode is in contact connection with the front electrode, and extends onto the insulating layer. A taper angle is formed between a periphery of the insulating layer and the front electrode, and the taper angle ranges from 35° to 75°.
