专利汇可以提供Thin film solar battery专利检索,专利查询,专利分析的服务。并且PURPOSE:To improve the efficiency of a thin film solar batter by forming the surface not faced with the junction surface of one of two types of semiconductor layers forming hetero junction in porous state, thereby substantially decreasing the thickness of the semiconductor layer. CONSTITUTION:After a CdS layer added with approx. 10% of CdCl2 is coated on a glass substrate 7, the layer ia baked to obtain a CdS layer 8. After a CdTe layer added with less than 1wt% of CdCl2 amount is coated by a printing a screen of 10mum of emulsion thickness of stainless steel screen of 400 mesh, it is baked in a furnace of 620-680 deg.C and 80-120mm./min of belt speed (which is three times of the conventional speed) to obtain a CdTe layer 9 with porous surface. Ohmic electrodes 10, 11 are formed on the layer 9. The porous layer substantially decreases the thickness of the layer 9.,下面是Thin film solar battery专利的具体信息内容。
