Conjugated polymers were also used in this type of photovoltaic cell. Its sensitivity is not flat, but it is same as that of Silicon photovoltaic cell. There are a range of emerging photovoltaic cell technologies used in these systems. Photovoltaic cell electrical output is extremely sensitive to shading. Richard Swanson is the retired founder of the SunPower, a solar photovoltaic cell manufacturer. Indosolar Limited is an Indian photovoltaic cell and solar panel manufacturer. The first photovoltaic cell ever designed was also the first photoelectrochemical cell. In the early 1940s, the photovoltaic cell was developed by Russell Ohl.
