The utility model relates to a solar cell and solar cell module. Solar cell module contains solar cell, solar cell has silicon base layer, and its rear surface has aluminum shot sublayer and the backsign layer on some on some. Back sign layer includes, improvement aluminum shot sublayer in the basic unit to and direct improvement intercalation on improveing the aluminum shot sublayer. The improvement intercalation has the solderable surface of keeping away from silicon base layer. Improvement aluminum shot sublayer includes aluminum shot and comes from the at least a material of improveing the intercalation. The improvement intercalation includes the noble metal to and bismuth, boron, indium, lead, silicon, tellurium, tin, vanadium, zinc and combination is arbitrary. 本实用新型涉及太阳能电池及太阳能电池模块。所述太阳能电池模块包含太阳能电池；所述太阳能电池具有硅基层，其后表面具有部分上的铝粒子层和部分上的后标志层。后标志层包括，基层上的改良铝粒子层，以及直接在改良铝粒子层上的改良插层。改良插层具有远离硅基层的可软焊表面。改良铝粒子层包括铝粒子和来自改良插层的至少种材料。改良插层包括贵金属，以及铋、硼、铟、铅、硅、碲、锡、钒、锌及其组合的任意。
