摘要： The present invention discloses a laser-scribing method to make a bifacial thin film solar cell and the structure thereof. The laser-scribing method is to form scribing patterns that penetrate different structural layers during the process of forming various structural layers. After the laser-scribing, the top solar cell unit is attached with the bottom solar cell unit by various combining steps to form a solar cell assembly. The solar cell assembly can receive light from both sides via the absorber layers of both of the top solar cell unit and the bottom solar cell unit. The solar cell assembly has an increased output efficiency and a greater power density and the cost of the manufacturing is therefore reduced.
