Lead-free double halide perovskite Cs 3 BiBr 6 with well-defined crystal structure and high thermal stability for optoelectronics
Halide perovskites have continued to rise as attractive light absorber materials, mainly driven by their potential wide applications in the fields of solar cells, photodetectors, lasers and others. However, Pb-containing perovskites are poisonous and could cause serious potential problems to our environment. Thus, there is a strong desire to develop lead-free perovskites as environmentally friend
