A solar collector produces a maximum temperature of 98 °C using concentrated sunlight. This energy is used in a heat engine that operates in a 10°C environment. If the solar collector is redesigned to focus the sunlight and reach a higher temperature, what should the maximum temperature be (in °C) to double the efficiency, assuming the heat engine is a Carnot cycle?

A solar collector produces a maximum temperature of 98 °C using
concentrated sunlight. This energy is used in a heat engine that operates
in a 10°C environment. If the solar collector is redesigned to focus the
sunlight and reach a higher temperature, what should the maximum
temperature be (in °C) to double the efficiency, assuming the heat engine
is a Carnot cycle?
