Title: Manufacture of integrated type solar battery
Inventor: NIHEI KAZUYA
IPC: H01L31/04
Filed: 1985-11-08
Abstract: PURPOSE:To improve output characteristics, by etching an impurity doped layer of a semiconductor thin film at the exposed part of a surface, simultaneously removing photoresist for patterning of a metal electrode, thereby removing the impurity-doped layer, i.e., a high-conductivity part, and making a parallel resistance large. CONSTITUTION:A plurality of transparent electrodes 2 and a plurality of a-Si regions 3 in a P-I-N structure are formed. Then a metal film is deposited on the entire surface by evaporation or sputtering. The film is divided on the a-Si layer by photolithography, and metal electrodes 4 are formed. Thereafter, photoresist 7 remaining on the metal film is removed with alkaline-removing liquid. An exposed part 6 of the a-Si layer is etched. Thus a part of the N-layer or the entire N layer doped with impurities on the a-Si layer 3 is removed, and a sheet resistance becomes large. At this time, an etching depth 8 of the a-Si layer is adjusted, and a parallel resistance 43 is made large without the effect on the characteristics of the solar battery. Thus the characteristics of the solar battery can be improved.

Filed: 1989-09-29
Abstract: PURPOSE:To simplify a circuit by detecting the voltage and the current of a power driving a transmitter and by controlling a transmission frequency so that a phase difference between them becomes small. CONSTITUTION:In the present transmitter, a voltage V1 is taken out from the opposite ends of a high resistor R1 connected to an output transformer 3, while a current converted into a voltage V2 is taken out from the opposite ends of a low resistor R2, and these voltages V1 and V2 are inputted to a control circuit 4. In this case, the sharpness Q of resonance is determined by Q=f0/(f2-f1), and when a point of resonance is located at a frequency f0, a phase difference between the voltages V1 and V2 is zero. When the relation between reactance and frequency is as shown in the figure, the phase difference becomes large when transmission is made with the frequency f0. Therefore the frequency is varied so that the phase difference be small, and since the phase difference is zero at a frequency of f3, the transmission is made with the frequency of f3.
