The sun offers the most abundant, reliable and pollution-free power in the world. However, problems with solar energy, namely the expensive cost and inconsistent availability, have prevented it from becoming a more utilized energy source.
The existing photovoltaic(PV) module on the market has a problem in that a certain amount of power generation is possible even in cloudy or cloudy weather, but the efficiency is lowered. On the other hand, the high-concentration module(CPV) previously developed by a Korean company to be introduced can generate high efficiency when the sun's light is good, but the power generation is zero when the weather is cloudy.
For this reason, the Korean company specialized in manufacturing photovoltaic power generation developed a CPV+PV combined solar module which is designed to maintain the highest performance and durability at a very competitive cost.
Each module has 36 triple-junction high efficient power elements and is designed to accommodate the solar light of incident angle of +-7 through the optical system. It maintains the best light transmittances and long-term durability by using a PC-plane lens and is designed to keep the device at the proper temperature by adding a heat sink. The high-efficiency hybrid technology enables a realization of the more economic integrated power generation system.
**Characteristics and functions of CPV + PV module
- Combination of silicon solar cell and triple-junctioned high efficient power generation device
- Built-in(embedded) bypass diode
- Low thermal resistance
- CTJ cells are connected by gold (Au) bonding
- PC plane lens
- Aluminum frame
- Aluminum external heatsink added
Based on its competences and experiences, the company wishes to find partners with the demands of such a solution and expand its market across the globe. Under a license agreement, the company’s willing to transfer its know-how and rights of the technology in return for a fee or share of royalties. Under a commercial agreement with technical assistance, the company can provide some assistance with starting up an installation for a purchaser, as well as with some technical consultancy of its maintenances.
