SEMICONDUCTOR PHOTOELECTRIC TRANSDUCER Russian patent published in 2002 - IPC

FIELD: solar-to-electric energy conversion; designing contacts for such converters. SUBSTANCE: converter has semiconductor plate 1 with contact grid on its face side; the latter is assembled of narrow current-collecting strips 2 passing without open circuit in parallel with transversal axis and spaced through definite distance apart; they are crossed at angle of 90 deg. by two wider current-collecting strips 3 arranged symmetrically on either side of longitudinal axis; these strips are widened at ends to form octagon-shaped pads 4 for connecting metal buses and on sides to organize triangle-shaped area of 0.5-0.9 sq. mm. EFFECT: enhanced service life and mechanical strength of contacts. 5 cl, 2 dwg
