“…The calculated QE broadly agrees with earlier experimental studies [8], giving confidence that the model gives a realistic estimate for the photogeneration in the multi-junction solar cell. The InGaP and InGaAs absorption coefficients were calculated from the model dielectric function (MDF) approach of Adachi [9].…”

A multi-junction concentrator system computer model is presented, that aims to accurately m odel the power generated based on environmental data input, such as the irradiance, air temperature, humidity and pressure. The device model is discussed, illustrating the importance of statistical variation of module components when simulating a multi-cell module. This comprehensive concentrator computer model will be released for general use, aiming to become a useful resource for those designing and testing multi-junction based concentrator systems.

“…18 The result can be summarized by the equation listed in the Figure 8 as a function of the short-circuit current density for that instance. 15,[18][19][20][21] The relative value of the coefficient logarithmically drops with the increase of the current density. Now, the cell temperature of the concentrator cell is not always the module temperature measured by a thermocouple mounted on the module body.…”

The status of the development of a new concentrator module in Japan is discussed based on three arguments, performance, reliability and cost. We have achieved a 26Á6% peak uncorrected efficiency from a 7056 cm 2 400Â module with 36 solar cells connected in series, measured in house. The peak uncorrected efficiencies of the same type of the module with 6 solar cells connected in series and 1176 cm 2 area measured by Fraunhofer ISE and NREL are reported as 27Á4% and 24Á8% respectively. The peak uncorrected efficiency for a 550Â and 5445 cm 2 module with 20 solar cells connected in series was 28Á9% in house. The temperature-corrected efficiency of the 550Â module under optimal solar irradiation condition was 31Á5 AE 1Á7%. In terms of performance, the annual power generation is discussed based on a side-by-side evaluation against a 14% commercial multicrystalline silicon module. For reliability, some new degradation modes inherent to high concentration III-V solar cell system are discussed and a 20-year lifetime under concentrated flux exposure proven. The fail-safe issues concerning the concentrated sunlight are also discussed. Moreover, the overall scenario for the reduction of material cost is discussed.

“…In the literature devoted to terrestrial applications, attention to temperature behavior of SCs is focused on the intervals above 0ºC [2][3][4][5]. In order to realize the full potential of the cells with regard to current matching and power extraction under different conditions of operation, a full set of parameters under temperature and irradiance variation is of great interest.…”
