Problems solved by technology

However, due to TiO 2 The band gap is relatively large, and the above patents all have the disadvantages of narrow spectral response range and low utilization rate of sunlight, which leads to low photoelectric conversion efficiency of solar cells
So far, no one has reported that it can improve TiO 2 The interface contact effect of nanorod array heterojunction solar cells can also broaden the research work of its light absorption range
