    Abstract: A method for preparing a perovskite solar cell module by roll-to-roll printing compri-sing preparing a perovskite solar cell functional layer and a back electrode on a subs-trate by use of a roll-to-roll process with a solar cell production equipment to obtain a perovskite solar cell slice, i.e., a solar cell module. The functional layer comprises a hole transport layer, a perovskite layer and an electron transport layer； wherein th-e solar cell production equipment comprises a near infrared heating system and an a-ir heating system to heat synergistically when the perovskite layer is being prepared. The method can realize automatic, continuous and large-scale production, and can re-alize the efficient and rapid preparation of the perovskite solar cell. The area, size an-d shape of the resulting perovskite modules can be flexibly controlled as required, s-uch that a perovskite solar cell modules can be formed with the benefit of saving raw materials and adapting to the market requirements.

    Abstract: A switched capacitor charge pump driver for a piezoelectric actuator is provided. The switched capacitor charge pump driver includes a power source, a first capacitor and a piezoelectric actuating circuit. The first capacitor is charged by the power source during a first state and discharged to the piezoelectric actuator in the piezoelectric actuating circuit during a second state. The switched capacitor charge pump driver can expand the application of a charge controller to a broader frequency range, especially at low frequencies, and can effectively decrease the hysteresis of a piezoelectric stack over a large frequency range even at a quasistatic state. A method for driving a piezoelectric actuator by a switched capacitor charge pump is further provided.
