Abstract Recent years, because of serious energy and environmental problems, some new energy technologies are developing in the world. One of the promising new energy technologies is Photovoltaic cell (PV cell). But PV cell has many problems such as high cost and low power density. In this study, we tried to do enhancement of PV cell power output at low cost. So, we produced a few Solar Energy Collecting Photovoltaic cells with plane mirror (SEC-PV), and we tested this new system (SEC system). The results are as follows : (1) PV cell power output is able to increase by the area ratio of plane mirror, and the limit of increase is about 2.0. (2) Installation angle of plane mirror is decided by the area ratio of plane mirror and PV cell. (3) Maximum electric energy ratio by this SEC system is about 1.18, and in this case, the area ratio of plane mirror and PV cell is about 1.0.
