Utilization of solar cells as a power source at this time is so much less. Many reasons were revealed, both the efficiency of the problems until the physical form is not attractive. But for the last factor, can now be addressed by researchers from Michigan State University who managed to create transparent solar cells.
This achievement was expected to further increase the level of use of solar cells in buildings. With the transparent form, then the integration of solar cells in windows can be done easily. It also managed to solve the problems encountered by ordinary solar cells.
