Consider a Si p-n junction solar cell of area 2 cm². The device delivers the maximum load current of 90 mA. If the dopings of the solar cell are Na= 5 x 10 cm, N. = 107cm- and the junction saturation current I. = 5 x 10%/N, A. (a) Calculate the open-circuit voltage when the cell is operating at 37 °C; (b) If a solar concentrator is used and the solar intensity increase by a factor of 10. Calculate the open-circuit voltage and compare its efficiency with the result of part (a). (c) Estimate the maximum achievable power of the concentration solar cell at 37 °C that the photon
