The embodiment provides a method and an apparatus for manufacturing a semiconductor element showing high conversion efficiency and having a perovskite structure. The embodiment is a method for manufacturing a semiconductor element comprising an active layer having a perovskite structure. Said active layer is produced by the steps of: forming a coating film by directly or indirectly coating a first or second electrode with a coating solution containing a precursor compound for the perovskite structure and an organic solvent capable of dissolving said precursor compound; and then starting to blow a gas onto said coating film before formation reaction of the perovskite structure is completed in said coating film. Another embodiment is an apparatus for manufacturing a semiconductor element according to the above method.

A power supply system of an embodiment has a plurality of power conditioners, an acquisition device, and a search instruction generator. The power conditioners convert a form of electrical power generated by a plurality of electrical generators into a different form of electrical power. The acquisition device acquires a respective information regarding power output from each of the plurality of power conditioners. The search instruction generator generates and outputs an operating point search instruction to one or more power conditioners being lower in a ratio of output power with respect to a reference power by at least a prescribed degree than one or more different power conditioners, wherein the reference power is given, based on the maximum output power or rated power of the corresponding electrical generator, or based on the maximum output power or rated power of the power conditioner.

Power supply system

An apparatus is disclosed that includes a resistance measuring unit operable to determine a solution resistance Rsol and a charge transfer resistance Rct of a battery; and at least one computer-readable non-transitory storage medium comprising code, that, when executed by at least one processor, is operable to provide an estimate of the present value of the battery by: comparing Rsol and Rct to historical deterioration transition information; estimating the number of remaining charge cycles before a discharge capacity lower limit is reached by the battery using the comparison; and estimating the number of remaining charge cycles before a discharge time lower limit is reached by the battery using the comparison. The estimate of the present value of the battery includes the smaller of the number of remaining charge cycles before a discharge capacity lower limit is reached or the number of remaining charge cycles before a discharge time lower limit is reached.
