P-N junction01:11

P-N junction

852
A p-n junction is formed when p-type and n-type semiconductor materials are joined together. At the interface of the p-n junction, holes from the p-side and electrons from the n-side begin to diffuse into the opposite sides due to the concentration gradient. This diffusion of carriers leads to a region around the junction where there are no free charge carriers, known as the depletion region. The charge density within the depletion region for the n-side and p-side can be described by the...

Area of Science:

  • Photovoltaics and Renewable Energy
  • Metrology and Measurement Science

Background:

  • Growing interest in indoor energy harvesting for Internet-of-Things (IoT) devices necessitates accurate characterization of light-harvesting solar cells.
  • Current methods for measuring indoor light irradiance, such as illuminance meters, exhibit significant inter-laboratory discrepancies.
  • Standardized testing conditions are lacking for indoor photovoltaic (PV) devices, unlike well-established outdoor solar module rating conditions.

Purpose of the Study:

  • To establish a more accurate and reproducible method for measuring irradiance from indoor ambient lighting for solar cell characterization.
  • To propose a standardized approach that facilitates inter-laboratory comparisons and accurate power conversion efficiency calculations.
  • To initiate a dialogue among National Metrology Institutes for drafting standards for indoor solar cell testing.

Main Methods:

  • Utilizing a calibrated reference solar cell to measure the total irradiance of the test light source.
  • Establishing multiple reference indoor lighting spectra with defined illuminance and precise spectral irradiance profiles.
  • Employing the reference solar cell to set the test light level before and during the collection of current-voltage (I-V) characterization data.

Main Results:

  • Demonstrated a method for creating reference indoor lighting spectra that meet specific illuminance and spectral profile requirements.
  • The proposed method provides a more accurate measure of irradiance compared to traditional illuminance meters.
  • The approach enables consistent and reliable measurements across different laboratories.

Conclusions:

  • The developed method offers a viable solution for accurate irradiance measurement in indoor solar cell testing.
  • This approach is crucial for reliable power conversion efficiency calculations and inter-laboratory data comparability.
  • The proposed methodology serves as a foundation for developing international standards for indoor PV device characterization.
