Light Emitting Transistors and Photovoltaics

We just in the past weeks invented light emitting transistors [LET] which turn electric signal into photos by an electrochemical process. This process can be reversed to turn photons into electricity more directly than a photovoltaic cell. We should reverse engineer this process to advance photovoltaic technologies.

"“With LETs, we could develop an optical interconnection beyond the present copper interconnection,” Shin-Ichi Saito, co-author of the study in Applied Physics Letters, told PhysOrg.com."
