Abstract

Disclosed herein is a device for controlling a sample temperature during photoelectric measurement of the sample. The device for controlling a sample temperature during photoelectric measurement of the sample includes: a sample stage to which a measurement target sample is fixed; a cooling unit for cooling the sample by injecting air; and a temperature measuring unit having a thermometer that measures a temperature of the sample. The device has an effect of easily controlling the temperature of a measurement target sample by employing a direct control method for a sample temperature, in which air or cooled air is injected to the sample.

First claim

1 . A device for controlling a sample temperature during photoelectric measurement of the sample, comprising:
a sample stage to which a sample is fixed, the sample being a measurement target; a cooling unit for cooling the sample by injecting air; and a temperature measuring unit having a thermometer to measure a temperature of the sample.

2 . The device of claim 1 , wherein the cooling unit comprises:
an air compressor for generating compressed air; and a compressed air injector, connected to the air compressor, for injecting compressed air.

3 . The device of claim 2 , wherein the cooling unit comprises a compressed air cooler, connected to the air compressor, for cooling compressed air.

4 . The device of claim 2 , further comprising a first stand to which the compressed air injector is connected.

5 . The device of claim 4 , wherein the compressed air injector is connected to the first stand using a first connection element, and the first connection element or the compressed air injector has mobility in one or more directions.

6 . The device of claim 1 , further comprising a second stand to which the thermometer is connected, wherein the thermometer is a non-contact thermometer.

7 . The device of claim 6 , wherein the thermometer is connected to the second stand using a second connection element, and the second connection element or the thermometer has mobility in one or more directions.

8 . The device of claim 1 , further comprising
a control unit for controlling an amount of air injected or generated from the cooling unit according to a temperature measured in the temperature measuring unit.

9 . The device of claim 1 , wherein the sample stage has cooling equipment to cool the sample stage.

10 . The device of claim 9 , wherein the cooling equipment cools the sample stage using water cooling or thermoelectric cooling.

11 . The device of claim 9 , wherein the sample stage has a contact temperature sensor to measure a temperature of the sample stage.

12 . The device of claim 9 , wherein the sample stage is supported by a supporting unit, which contacts with at least one part of the sample stage.

13 . A solar cell measurement device, comprising:
a light source unit having a light source that emits light; a sample stage to which a sample is fixed, the sample being a measurement target; a cooling unit for cooling the sample by injecting air; and a temperature measuring unit having a thermometer to measure a temperature of the sample, wherein the sample is one selected from among a solar battery unit cell, a solar battery module, and a sub-assembly of a solar battery cell.

14 . The solar cell measurement device of claim 13 , wherein the light source is one selected from among a xenon lamp, halogen lamp, LED, and a combination thereof.

15 . The solar cell measurement device of claim 13 , wherein the cooling unit comprises:
an air compressor for generating compressed air; and a compressed air injector, connected to the air compressor, for injecting compressed air.

16 . The solar cell measurement device of claim 15 , wherein the cooling unit comprises a compressed air cooler, connected to the air compressor, for cooling compressed air.

17 . The solar cell measurement device of claim 15 , further comprising a first stand to which the compressed air injector is connected.

18 . The solar cell measurement device of claim 13 , further comprising a second stand to which the thermometer is connected, wherein the thermometer is a non-contact thermometer.

19 . The solar cell measurement device of claim 13 , further comprising a control unit for controlling an amount of air injected or generated from the cooling unit according to a temperature measured in the temperature measuring unit.

20 . The solar cell measurement device of claim 13 , wherein the sample stage has a contact temperature sensor to measure a temperature of the sample that is in contact with the sample stage and cooling equipment to cool the sample that is in contact with the sample stage.
