Abstract
A plurality of photovoltaic devices (e.g., solar cells) connect with each other and form a photo-electric conversion apparatus. The photovoltaic devices concerned are so connected with each other that when a given pattern of light is irradiated upon the photo-electric conversion apparatus concerned, the electrical output generated when the whole of it is irradiated is smaller than that generated when some parts of it are irradiated. Since an electronic system equipped with this apparatus as a power supply can be designed to work when the apparatus is irradiated with such a pattern of light that irradiates only a part of the apparatus, an electronic system having such an identifying faculty can be made easily. Further, an apparatus like this type may be made by connecting the elements of this apparatus in series or in reverse direction to form units, and by connecting this plurality of units in series and/or in parallel.
