To improve the efficiency of PV modules, the back is laminated so that the PV modules confine radiation. Because of this, the generated output is improved, but the back of the modules is shaded. If a transmission-type PV module is applied, the conversion efficiency is reduced. However, by utilizing light transmitted from the back, it is possible to expand the applications for the back surface to utilize transmitted light.

Transparent OPV (Organic PhotoVoltaic) that can add a value of photosynthesis in addition to the power generation. This transparent OPV emits blue and red light effective for photosynthesis. In this study, investigation was carried out for a certain period of time, the evaluation of the power generation characteristics and the transmitted light characteristics of OPV were examined.

This paper recommends to use transparent OPV in a greenhouse. Output and transmitted light characteristic of transparent OPV attached to a small size greenhouse were measured.

As a result, effective transmitted light for photosynthesis was confirmed concurrently with power generation function. The optimal arrangement direction of the cells was confirmed when transparent OPV attached to a small size greenhouse. And spectral solar radiation of transmitted light on the horizontal surface and on the curved surface was confirmed.
