碩士 === 南臺科技大學 === 電子工程系 === 105 === This study presents a new type of third generation solar cell called the Perovskite Solar Cells. Solar cells are mainly composed of a hole transport layer, an active layer, and an electron transport layer (P-I-N junction). When the active layer is stimulated by the sun, it yields electrons and holes, thereby producing a voltage between the ionized P pole and N pole. This thesis is divided into two main parts: the component fabrication of the Perovskite Solar Cells and the design of solar energy blocks for teaching. In the components fabrication, we utilized a spin coating machine to sputter coat on a fluorine doped tin oxide (FTO) glass substrate using two materials, Titanium Oxide (TiO2) and Perovskite materials (CH3NH3PbI1Cl2), to produce the electron transport layer of the calcium titanate solar cell and the active layer. The iodonium copper (CuI) is then sputtered on the surface through the DC sputtering method to produce the hole transport layer. With the use of a Scanning Electron Microscope, we were able to observe the thickness of the TiO2 at different rotational speeds as well as the film forming uniformity of CuI. Subsequently, a solar energy simulator was used to measure the I-V characteristics of the solar cell products. The result showed that the perovskite solar cells produced could yield a 16.8% conversion efficiency. In addition, the solar energy blocks for teaching had each layer of the solar cell material designed into a game of building blocks that uses individual blocks with embedded RFID chips. The operator must stack the correct structure within the time limit to pass the test. When the operator is in doubt of a block during the process of the game, the operator can place the block on the RFID sensing device. The computer, in turn, conveys the role and the name of the material for the particular solar cell block. We hope that through the game, nonprofessionals would learn about the structure of solar batteries in a lively and relaxed way.
