Temperature, illumination and fluence dependence of current and voltage in electron irradiated solar cells

Emperical equations have been derived from measurements of solar cell photovoltaic characteristics relating light generated current, IL, and open circuit voltage, VO, to cell temperature, T, intensity of illumination, W, and 1 Mev electron fluence, phi both 2 ohm-cm and 10 ohm-cm cells were tested. The temperature dependency of IL is similar for both resistivities at 140mw/sq cm; at high temperature the coefficient varies with fluence as phi 0.18, while at low temperatures the coefficient is relatively independent of fluence. Fluence dependent degration causes a decrease in IL at a rate proportional to phi 0.153 for both resistivities. At all intensities other than 560 mw/sq cm, a linear dependence of IL on illumination was found. The temperature coefficient of voltage was, to a good approximation, independent of both temperature and illumination for both resistivities. Illumination dependence of VOC was logarithmic, while the decrease with fluence of VOC varied as phi 0.25 for both resistivities

Severe gynaecomastia associated with highly active antiretroviral therapy

The association between gynaecomastia and HIV infection was first reported in 1987; however, there were no subsequent published reports of gynaecomastia linked to HIV infection until highly active antiretroviral therapy (HAART) was introduced. Although HAART significantly improves the prognosis of HIV infection, its extensive use has resulted in multiple adverse effects, including benign breast enlargement. We present a rare case of severe gynaecomastia in a male patient with vertically transmitted HIV on HAART. He was surgically treated with mastectomy with no nipple-areolar complex reconstruction. The pathology report confirmed the benign nature of the breast tissue. Surgical intervention resulted in an improvement of daily activities and enhanced psychosocial wellbeing. Benign bilateral breast enlargement of this magnitude in a male patient has never been reported. Keywords: gynaecomastia; HIV; highly active antiretroviral therapy; efavirenz
