The Ministries of Energy and Agriculture are launching a first-of-its-kind program to optimize the use of agricultural land and integrate clean electricity production, accompanied by research to examine the effects on agricultural production. According to estimates, this is a total area of ​​about 2,000 dunams

In the figure you can see the ratio between the photovoltage and photocurrent in the photoanode for different radiation concentration levels. As the radiation intensity increases, there is a significant increase in photocurrent. Similar to solar cells, for low voltage photovoltaics, this increase is directly proportional to the radiation intensity. In addition, with the increase in radiation intensity, the photovoltage built up in the electrode also increases. Since the addition of photovoltage comes in addition to the increase in current, there is an increase in the efficiency of the energy conversion. On the side of the graph you can see an illustration of the experimental system. The light comes from a light source that simulates sunlight. This light is focused on the photoanode with the help of a lens. The intensity of the radiation affecting the electrochemical cell is determined by the distance between the photoanode and the lens
