Crystalline silicon cell, which takes a large proportion in the photovoltaic industry, possesses complicated productive process and relatively high manufacturing cost, hence the study of new solar cell technique has been gaining increasing attention. The perovskite material shows excellent photovoltaic property with simple manufacturing process easy access of all the materials needed, thereby has a promising future in the photovoltaic industry. In the paper, we put forward a new assemble technique of perovskite solar cell according to its requirement of stability of the device, and design a household photovoltaic power generation system under the condition that transmission and distribution system are not convenient . The design includes the calculation of accumulator capacity, and the choice of controller and inverter. The performance of the perovskite solar cell device is verified through tests, which also inspires a new thinking for future household photovoltaic power generation system design.
