太阳能电池及其制造方法
摘要：
根据一个实施方案的太阳能电池包括：基础衬底；形成在基础衬底上的背电极层；形成在背电极层上的光吸收层；形成在光吸收层上的缓冲层；形成在缓冲层上的高电阻缓冲层；以及形成在高电阻缓冲层上的前电极层。孔穿过光吸收层和缓冲层。根据一个实施方案的用于制造太阳能电池的方法包括：在衬底上形成背电极层的步骤；在背电极层上形成光吸收层的步骤；在光吸收层上形成缓冲层的步骤；对缓冲层的一部分进行蚀刻的步骤；以及在缓冲层上形成前电极层的步骤。
摘要（英）：

The solar cell according to one embodiment comprises: a base substrate; a back electrode layer formed on the base substrate; an optical absorption layer formed on the back electrode layer; a buffer layer formed on the optical absorption layer; a high-resistance buffer layer formed on the buffer layer; and a front electrode layer formed on the high-resistance buffer layer. A hole penetrates through the optical absorption layer and the buffer layer. The method for manufacturing a solar cell according to one embodiment comprises: a step of forming a back electrode layer on a substrate; a step of forming an optical absorption layer on the back electrode layer; a step of forming a buffer layer on the optical absorption layer; a step of etching a portion of the buffer layer; and a step of forming a front electrode layer on the buffer layer.
