Research Center for Photovoltaics

 

Research Teams & Themes

The RCPV consists of the following 8 teams. Click each team name for more information on each team's research.
 
Calibration, Standards and Measurement Team ( CSMT )

We develop accurate photovoltaic (PV) performance characterization technologies and PV reference device calibration technologies, contributing to the improvement of international competitiveness and mass deployment of PV technologies through the establishment of international conformity of the calibration and measurement technologies.

PV System and Application Team ( PVSAT )

PV System and Application Team (PVSAT) is only the team that considers PV system not to be a photovoltaic device but to be a power generation system. Our team’s research objective is to improve “PV system for the welfare of PV users” and “PV system as a player of energy infrastructure”.

Module Reliability Research Team ( MRRT )

Photovoltaic modules with improved reliability and long lifetime are developed using novel module materials, for example, encapsulant, backsheet, interconnector, sealant, etc.  Test methods for characterization of module lifetime are also developed.  Both energy yield and reliability for photovoltaic modules set in the outdoor site are characterized.

Compound Semiconductor Thin Film Team ( CSTFT )

We reveal the essential mechanisms which lead high-efficiency solar cells and develop the advanced device processing technologies to overcome the difficulties, particularly for compound semiconductor thin-film solar cells, such as CIGS and CZTS solar cells. We also introduce the developed technologies to industrial sectors,             and contribute to the development of solar cell industries in Japan.

Advanced Processing Team ( ADPT )

In order to achieve massive deployment of photovoltaic systems, it is essential to reduce the cost of solar cells. At the Advanced Low Cost Processing Team, we are developing technologies to realize low-cost solar cells. In particular, thin-film solar cells are advantageous in resource conservation and large-area processing. We are focusing on thin-film silicon solar cells.

Smart Stack Device Team ( SSDT )

Cost reduction and improved conversion efficiency are the most important issues facing the wide-scale deployment of solar photovoltaic systems. Although multijunction solar cells have the highest reported efficiencies and have been commercialized for space and concentrator applications, their use has not become widespread due to their high cost. Our objective is to develop advanced multijunction technologies with extremely low cost and high conversion efficiency.

Functional Thin Films Team ( FTFT )

Organic-based thin-film solar cells are advantage in resource conservation and large-area processing. We are focusing on organic-based solar cells which began to develop toward the practical use.

Advanced Functional Materials Team ( AFMT )

(1)Improvement of efficiency on dye-sensitized solar cell using new sensitizers for near-IR light utilization.
  (2)Development of artificial photosynthesis technologies using photoelectrode and photocatalyst.
  (3)Development of fundamental technologies to use solar energy efficiently.
