We combine monolayer TMD with chiral lead halide perovskites to achieve enhanced valley polarization via chirality induced spin selective charge transfer and to demonstrate the utility of chiral perovskites as spin filters, preferentially injecting charges with one spin, depending on the handedness of the perovskite material. This elegant, yet simple way to control valley polarization does not require circularly polarized light, and can be realized at room temperature, without a need for cryogenic temperatures, usually implying expensive, bulky, complex setups. Achieving robust valley polarization in TMDs at room temperature is of great importance for practical applications of TMD based valleytronics devices in quantum information science and technology.
